Scope mount

January 01, 1970

Scope mounts are rigid implements used to attach (typically) a telescopic sight or other types of optical sights onto a firearm. The mount can be made integral to the scope body (such as the Zeiss rail) or, more commonly, an external fitting that clamp onto the scope tube via screw-tightened rings (similar to pipe shoes). The scope and mount are then fastened onto compatible interfaces on the weapon. Words such as mounts and bases are used somewhat loosely, and can refer to several different parts which are either used together or in place of each other as ways to mount optical sights to firearms.

Attachment interfaces for scope mounts vary according to weapon design and user choice. Traditionally scope mounts are fastened onto firearms via tapped screw holes (usually on the receiver) and/or clamps (onto the barrel or stock). Since the mid-20th century, dovetail rails, where the mount is slided over a straight dovetail bracket with an inverted isosceles trapezoid cross-section and fixed tight in position with clamping screws, became more common due to the ease of installation and removal. Later, the hexagonally cross-sectioned rail interface systems such as Weaver rail became popular and was later modified into the Picatinny rail in the early 1990s, which became the standardized military-use mounting interface for NATO troops in 1995. The Picatinny rail was officially replaced by the metrified NATO Accessory Rail for military use in 2009, although it remained popular in the civilian market for both scope and accessory mounting.

Scope mounts can be either one-piece (a single implement with multiple clamping rings) or multi-piece (usually two or more individual scope rings). These mounts are usually fastened with screws to specified tensions (which warrants the use of torque screwdrivers), but sometimes they are manually tightened via thumbscrews, and may even have Quick Release (QR) designs. As of 2020, the Picatinny rail is arguably the most widespread scope mounting standard for new firearms, although there are many proprietary and brand-specific types of mounts that can either be used with Picatinny rails, or as completely different design alternatives (see the section on Link between scope and firearm). Scope mounts may be offered by firearm and scope manufacturers, or bought as aftermarket accessories.

Zeiss rail edit

Among scopes for rail mounts, the 22.5-degree V-shaped Zeiss rail is the most prevalent standard. It was introduced in 1990. After the patent expired in 2008, compatible scopes have been offered from manufacturers such as Blaser,[1] Leica, Minox, Meopta, Nikon,[2] Noblex (formerly Docter[3]), Schmidt & Bender[4] and Steiner.[5] It has therefore, in some sense, become the de facto industry standard for scope mounting rails. The system has so far seen most use on the European high end market.[6]

Swarovski SR rail edit

The Swarovski SR rail (patented in 2002,[7][8][9] introduced in 2005[10] The Swarovski SR rail is also used by Kahles, a Swarovski subsidiary.[11]) has a flat rail with many "teeth" as recoil lugs, and is only offered on scopes from Swarovski and its subsidiary Kahles. It separates itself from the Zeiss rail in that it is not neither stepless nor self-centering.

S&B Convex rail edit

A former competing standard was the halv-circle shaped Schmidt & Bender Convex rail[4] also introduced in 2005. Schmidt & Bender after a few years changed to the Zeiss rail standard. In contrast to the Zeiss and Swarovski systems, the S&B Convex rail had the possibility to add a cant to the scope when mounting, such that the reticle is not horizontal to the ground.[12]

70-degree prism rail edit

There is an older European system with an upside-down V-shape (70 degrees).[13] This system has little widespread use today. The advantage of this system was that it at one time was offered by most European scope manufacturers, but the disadvantage was that the rail had to be drilled for a screw each time the eye relief was to be adjusted.[14] All new standards for rail mounts have addressed this issue.

Ring mounts usually consist of a base attached to the firearm and rings (usually two) attached to the sight. The rings are usually made of steel or aluminum. Common diameters on ring mounts are 25.4 mm (1 inch), 26 mm, 30 mm and 34 mm. There are big differences in the strength and ability of sustained precision on different assemblies. With weak cartridges such as .22 LR applied in light-use scenarios, a pair of skinny aluminium rings may work well, while firearms with very powerful recoil often combined with a heavy sight may require steel rings or thicker aluminum rings with recoil lugs to be used.

Sizes edit

Scopes for ring mounts are available in many different sizes. The most common ones are:

  • 1 inch (25.4 mm)
  • 30 mm
  • 34 mm

Some less common standards are:

  • 3⁄4 inch (19 mm)
  • 7⁄8 inch (22 mm)
  • 26 mm – Some older European scopes
  • 35 mm – Some IOR, Vortex and Leupold models
  • 36 mm – Some Zeiss and Hensoldt models
  • 40 mm – Some IOR models and Swarovski dS

Lapping edit

For a ring assembly to grip evenly, it is important that the scope rings are circular and coaxial with the scope tube. On ring mounts that grip unevenly, the ring mount can be lapped to prevent uneven pressure when mounting.[15] One scopes made for ring mounts, it is not uncommon to get ring marks when mounting the rings.

Ring inserts edit

There are insert rings on the market which allows for mounting a scope inside a ring mount of a larger diameter. An example could be to mount a scope with a 1-inch (25.4 mm) tube in a 30 mm mount using a plastic insert.

There are also special ring mounts in the market with circularly shaped ring inserts made to provide stress free mounting without lapping, with Burris Signature Rings and Sako Optilock Rings as two well-known examples. Burris Signature was introduced in 1995.[16] A patent was applied for in 1994, and was granted in 1995.[17] Sako Optilock has been sold since some time in the early 2000s.[18][clarification needed] The trade name Optilock was registered in the US in December 1997, and has been marketed in the US since December 2001.[19] In 2000, Sako was sold to Beretta Holding.[20] In 2002, Burris was also sold to Beretta Holding, and thus Burris and Sako got the same owners. Burris' original patent for the rings with the circular insertes was considered to have expired in 2014, and as of 2020 is listed as "definitely expired".[17]

In 2015, XTR Signature Rings was launched as a further development of the Burris Signature series. The XTR variant differs in that it has two circular cavities per ring assembly versus one.[21] A patent for the XTR Signature Rings was applied for in 2016, and was granted to Burris in 2019.[22]

Mounts for compact sights edit

Many reflex sights (e.g. red dot sights) and holographic sights have proprietary mounts.[23]

  • Aimpoint Acro rail: A dovetail rail for attaching a sight via a clamping mechanism, and with a 4 mm[24] wide straight recoil lug groove. The dovetail is approximately 16.5 mm wide, and is radiused so as not to have any sharp edges. The mount is compact enough to be used on pistols, as well as rifles and shotguns. Launched in 2019 together with the sights Aimpoint Acro P-1 and C-1.[25] Also used on Aimpoint Acro C-2 and P-2, as well as Steiner MPS.
  • Aimpoint Micro standard: First introduced in 2007[26] on the small tube sight variants of Aimpoint, but today used by other manufacturers as well. Popular on rifles and shotguns, but not on handguns due to its size. The mounting standard uses four screws and one cross slot acting as a recoil lug. Used on red dot sights such as Aimpoint Micro, Vortex Crossfire, Sig Sauer Romeo 4 & 5, and some Holosun Paralow variants.[23]
  • Aimpoint CompM4 mount: Launched in 2007[27] with the Aimpoint CompM4 sight. The sight is attached to the mount via two M5 screws from the underside, and the mount has a transverse groove acting as a recoil lug. The Aimpoint Comp line was launched in 1993.[27] The predecessor of the CompM4, CompM2, had a 30 mm ring mount and was introduced in the American military in 2000. Some manufacturers have copied the M4 mount system, but it has mainly been used by Aimpoint.[28][citation needed]
  • C-More standard: A mounting standard introduced by C-More Sights. Uses two screws and two circular notches acting as recoil lugs. Used on red dot sights such as Delta Optical MiniDot, Kahles Helia, Vortex Razor and Sig Sauer Romeo3.[23]
  • Docter/Noblex standard: The mounting pattern which through the 2010s was used by the largest number of manufacturers, perhaps due to the wide range of aftermarket mounts available. The mounting standard uses two screws and four circular notches acting as recoil lugs.[23] Used on red dot sights such as Docter/Noblex sights, Burris Fastfire, Vortex Viper, Leica Tempus, etc.
  • Shield standard: A proprietary standard used by Shield Sights. Similar in shape to the Noblex/Docter footprint, but with other dimensions.[23] In addition to the Shield red dot sights, it is also used on the Leupold Delta Point Pro.
  • Trijicon RMR/SRO-standard: Has two screw holes, and two shallow circular notches acting as recoil lugs.[23] Mainly used on the Trijicon RMR and SRO red dot sights, as well as on some Holosun sights.
  • Other: Some notable red dot sights which have unique footprints not compatible with any of the above are Sig Sauer Romeo 1, Holosun Paralow 403A,[23] Holosun 509T and Swampfox Kraken MRDS. There also exists reflex sights for ring mounts (e.g. Aimpoint CompM2 with a 30 mm tube) or with an integrated Picatinny base.

Link between scope and firearm edit

Bases edit

By bases, is usually meant an interconnecting part between the scope and the firearm. For example, a base may have a picatinny attachment on the underside, while the upper side may have either a ring (e.g. 30 mm) or rail mounting (e.g. Zeiss rail). On some assemblies, the upper and lower parts of the base are separate parts that must be screwed together and fastened to a specified torque.[29] A base can thus sometimes constitute a complete scope mount assembly, but is most often used to refer to the lower part of a two-part scope mount assembly.

The firearm interface which sits on the firearm and to which the scope mount is attached is often called the base or rail.

Some types of bases are:

Standard mounts
Proprietary and brand specific mounts
  • Claw mount. Several types, for example Suhl Claw Mounts,[30] Ziegler ZP mount, and others.
  • Pivot mount. Several types, for example EAW, MAKlick, Steyr Luxus, and others.[31]
  • Aimpoint Micro, also used by other red dot manufacturers.[32] (Not compatible with Aimpoint Comp or the Aimpoint ACRO mounting standards. See Red dot sight#Mounting types for more red dot mounting standards).
  • Blaser saddle mount[33]
  • Contessa 12 mm "Euro rail" mount[34][35]
  • Browning X-Lock[36]
  • Double dovetail, which is rotated and tapped into place.[37] Several types, for example the Leupold Dual Dovetail[38]
  • Mauser M03 Double Square Mount[39][40][41]
  • Picatinny-against-picatinny (Burris Eliminator[42])
  • Pulsar type rail mount. Has some visual similarities with the Zeiss rail, but is incompatible due to a wider base and steeper angle.[citation needed]
  • Redfield type[43] with windage adjustable mount, also known Redfield Standard Junior. Similar concepts are made by other manufacturers, e.g. "Leupold standard", "Burris TU/SU". Also manufactured by Weaver. Specifications can vary between manufacturers.[citation needed]
  • Ruger integral type (used on Ruger No. 1,[44] M77,[44][45] Gunsite Scout,[44][46] the Ranch series of the Mini-14[44][47] and Mini-30,[44] Deerfield Carbine,[citation needed] Model 96 (.44 Magnum only)[48] and PC Carbine.[49])
  • Sako Optilock,[50] either with rings separate from the bases, or with rings as part of the bases. Bases come in various variantes to fit either Sako tapered dovetail rail (available for three different types of action lengths), Tikka straight dovetail (11 mm or 17 mm), Weaver or Picatinny.
  • Sako tapered dovetail rail (used on SAKO models Sako 75, Sako 85, L461, L579, S491, M591, L61R, L691, M995 and TRG-S)
  • Sauer ISI mount (Sauer 303, and a very few editions of Sauer 202)[51]
  • Sauer SUM mount (Sauer 404)[51]
  • Schultz & Larsen integral Slide & Lock type[52][53]
  • "STANAG" Claw Mount, used on FN FAL, HK G3, HK33, G3SG/1 and MP5. Most STANAG bases must be used with corresponding STANAG rings, but there are also STANAG bases for scopes with rails.
  • Dovetail rail (for example 11 mm, 17 mm or 19 mm). The flank angle varies, and dovetail rail mounts may therefore be regarded as non-standardized, even for a given witdth.
  • Trijicon ACOG/VCOG rail
  •

Screw pattern on bases edit

On receivers without an integrated attachment for mounting a scope, for example, an integrated Picatinny rail, the base is usually screwed on as a separate part. Such mounts are often model-specific to the firearm, and depend on factors such as the radius of the receiver bridge, the type of screw and the distance between the screw holes. A common fastening method is by screws. These are often metric M3.5x0.6 mm or US #6–48 (⌀ 3.5 mm, 0.53 mm pitch) or #8–40 (⌀ 4.2 mm, 0.64 mm pitch).

Many European assemblies use M3.5 screws, such as SAKO Optilock, Recknagel and original CZ rings. Since #6–48 and M3.5x0.6 have near identical diameters and almost equal pitch, there is a potential for confusion, and upon mixing the wrong screw will enter the threads, but will gradually become tighter to screw until the thread is destroyed. In case of damage, the hole must often be drilled and re-threaded, and M4x0.7 or #8–40 may then be relevant alternatives.

Remington 700 pattern

The Remington 700 Short Action (SA) scope base attachment pattern is particularly widespread, and is for example used on models such as:[54]

The Remington 700 Long Action (LA) naturally has a longer distance between the front and rear screw holes, and therefore continuous scope mount assemblies for the 700 LA do not fit on the 700 SA nor the above-mentioned firearms. However, two-piece scope mounts in general interchange for the mentioned models.

List of common screw patterns

Bases with a rounded bottom for mounting on a round receiver bridges should ideally have a slightly smaller radius than the receiver in order to provide two points of contact and give a stable attachment. Conversely, a slightly too large radius on the mount will result in just one point of contact and a less stable attachment.

In the table below, the radius refers to the curvature of the mounting surface on the receiver bridge. The base is often attached with two screws on the front receiver bridge and two screws on the rear receiver bridge, but sometimes with several more screws. The hole distances are measured from center-to-center. Some common hole distances are 12.7, 15.37 and 21.84 mm (0.500, 0.605 and 0.860 in) respectively).[55]

The two front screws are referred to in the list below as screws 1 and 2, and the front hole spacing is thus referred to as «distance 1–2». In the same way, the rear hole distance is called «distance 3–4». The distance between these is largely determined by the receiver length, and is stated here as «distance 2–3»

Other features edit

Quick release edit

 
Picatinny ring mount with two quick-detach levers.

Quick release (QR) can refer to several different variants of scope mounts which can be mounted and disassembled quickly without tools.

Tilt edit

Main article: Milliradian § Adjustment range and base tilt

In some cases, it may be relevant to add extra inclination to the scope to be able to shoot at longer (or shorter) distance. For example, this is popular for long range shooting, where it is common to use a tilt of 6 mrad (20 MOA). Extra tilt can be achieved several ways, like for example with a tilted Picatiny rail (e.g. 6 mrad tilt), with bases or rings (e.g. 6 mrad tilt) or with special insert rings (e.g. Burris Pos-Align).[21]

Scope height edit

The height of scope sight can be important for the cheek rest support (often called cheek weld) to gain correct eye placement, as well as for calculating ballistics (e.g. a ballistic table). The latter is particularly relevant at very close ranges (e.g. 15 meters [49 feet]), while at longer distances, such as in long range shooting, the scope height has less impact on the ballistic calculations.

The height of a scope sight can be measured in many ways. With regard to ballistic calculations, it is generally only measured from the center of the bore axis to the center of the scope sight (sightline). With regard to cheek support, several methods are used: On firearms with a picatinny rail, the height is measured from the top of the picatinny rail on the firearm. On most other types of bases it is common to measure from the top radius of the receiver bridge.

When the bottom measuring point is determined, the height is then measured up to either the optical center or the bottom of the scope tube, on scopes for ring mounts. The difference between these two measuring methods is distance from the optical center to the bottom of the scope tube, and usually corresponds to half of the tube diameter (e.g. 15 mm on binoculars with a 30 mm tube).

are rigid implements used to attach typically a telescopic sight or other types of optical sights onto a firearm The mount can be made integral to the scope body such as the Zeiss rail or more commonly an external fitting that clamp onto the scope tube via screw tightened rings similar to pipe shoes The scope and mount are then fastened onto compatible interfaces on the weapon Words such as mounts and bases are used somewhat loosely and can refer to several different parts which are either used together or in place of each other as ways to mount optical sights to firearms A Leupold telescopic sight mounted on a dovetailed rifle receiver via two scope rings From left A sketch of a cross section on a Zeiss rail and ring mount both with a Picatinny rail interface Attachment interfaces for scope mounts vary according to weapon design and user choice Traditionally scope mounts are fastened onto firearms via tapped screw holes usually on the receiver and or clamps onto the barrel or stock Since the mid 20th century dovetail rails where the mount is slided over a straight dovetail bracket with an inverted isosceles trapezoid cross section and fixed tight in position with clamping screws became more common due to the ease of installation and removal Later the hexagonally cross sectioned rail interface systems such as Weaver rail became popular and was later modified into the Picatinny rail in the early 1990s which became the standardized military use mounting interface for NATO troops in 1995 The Picatinny rail was officially replaced by the metrified NATO Accessory Rail for military use in 2009 although it remained popular in the civilian market for both scope and accessory mounting Scope mounts can be either one piece a single implement with multiple clamping rings or multi piece usually two or more individual scope rings These mounts are usually fastened with screws to specified tensions which warrants the use of torque screwdrivers but sometimes they are manually tightened via thumbscrews and may even have Quick Release QR designs As of 2020 the Picatinny rail is arguably the most widespread scope mounting standard for new firearms although there are many proprietary and brand specific types of mounts that can either be used with Picatinny rails or as completely different design alternatives see the section on Link between scope and

degree V shaped Zeiss rail is the most prevalent standard It was introduced in 1990 After the patent expired in 2008 compatible scopes have been offered from manufacturers such as Blaser 1 Leica Minox Meopta Nikon 2 Noblex formerly Docter 3 Schmidt amp Bender 4 and Steiner 5 It has therefore in some sense become the de facto industry standard for scope mounting rails The system has so far seen most use on the European high end market 6 Swarovski SR rail edit The Swarovski SR rail patented in 2002 7 8 9 introduced in 2005 10 The Swarovski SR rail is also used by Kahles a Swarovski subsidiary 11 has a flat rail with many teeth as recoil lugs and is only offered on scopes from Swarovski and its subsidiary Kahles It separates itself from the Zeiss rail in that it is not neither stepless nor self centering S amp B Convex rail edit A former competing standard was the halv circle shaped Schmidt amp Bender Convex rail 4 also introduced in 2005 Schmidt amp Bender after a few years changed to the Zeiss rail standard In contrast to the Zeiss and Swarovski systems the S amp B Convex rail had the possibility to add a cant to the scope when mounting such that the reticle is not horizontal to the ground 12 70 degree prism rail edit There is an older European system with an upside down V shape 70 degrees 13 This system has little widespread use today The advantage of this system was that it at one time was offered by most European scope manufacturers but the disadvantage was that the rail had to be drilled for a screw each time the eye relief was to be adjusted 14 All new standards for rail mounts have addressed this issue Ring mounts edit nbsp An old German machinegun telescopic sight with scope rings nbsp Two Colt Python revolvers one above with barrel mounted scope nbsp A re enacted Confederate sharpshooter aiming a Whitworth rifle with a ring mounted scope secured by clamping onto the gunstock nbsp A one piece scope mount with three 30 mm rings on a Sako TRG 42 Ring mounts usually consist of a base attached to the firearm and rings usually two attached to the sight The rings are usually made of steel or aluminum Common diameters on ring mounts are 25 4 mm 1 inch 26 mm 30 mm and 34 mm There are big differences in the strength and ability of sustained precision on different assemblies With weak cartridges such as 22 LR applied in light use scenarios a pair of skinny aluminium rings may work well while firearms with very powerful recoil often combined with a heavy sight may require steel rings or thicker aluminum rings with recoil lugs to be used Sizes edit Scopes for ring mounts are available in many different sizes The most common ones are 1 inch 25 4 mm 30 mm 34 mm Some less common standards are 3 4 inch 19 mm 7 8 inch 22 mm 26 mm Some older European scopes 35 mm Some IOR Vortex and Leupold models 36 mm Some Zeiss and Hensoldt models 40 mm Some IOR models and Swarovski dS Lapping edit For a ring assembly to grip evenly it is important that the scope rings are circular and coaxial with the scope tube On ring mounts that grip unevenly the ring mount can be lapped to prevent uneven pressure when mounting 15 One scopes made for ring mounts it is not uncommon to get ring marks when mounting the rings Ring inserts edit There are insert rings on the market which allows for mounting a scope inside a ring mount of a larger diameter An example could be to mount a scope with a 1 inch 25 4 mm tube in a 30 mm mount using a plastic insert There are also special ring mounts in the market with circularly shaped ring inserts made to provide stress free mounting without lapping with Burris Signature Rings and Sako Optilock Rings as two well known examples Burris Signature was introduced in 1995 16 A patent was applied for in 1994 and was granted in 1995 17 Sako Optilock has been sold since some time in the early 2000s 18 clarification needed The trade name Optilock was registered in the US in December 1997 and has been marketed in the US since December 2001 19 In 2000 Sako was sold to Beretta Holding 20 In 2002 Burris was also sold to Beretta Holding and thus Burris and Sako got the same owners Burris original patent for the rings with the circular insertes was considered to have expired in 2014 and as of 2020 is listed as definitely expired 17 In 2015 XTR Signature Rings was launched as a further development of the Burris Signature series The XTR variant differs in that it has two circular cavities per ring assembly versus one 21 A patent for the XTR Signature Rings was applied for in 2016 and was granted to Burris in 2019 22 Mounts for compact sights edit nbsp Left Aimpoint Acro C2 reflex sight laying on its side Right Acro rail on a Picatinny riser nbsp Approximate Acro rail measurements Many reflex sights e g

meant an interconnecting part between the scope and the firearm For example a base may have a picatinny attachment on the underside while the upper side may have either a ring e g 30 mm or rail mounting e g Zeiss rail On some assemblies the upper and lower parts of the base are separate parts that must be screwed together and fastened to a specified torque 29 A base can thus sometimes constitute a complete scope mount assembly but is most often used to refer to the lower part of a two part scope mount assembly The firearm interface which sits on the firearm and to which the scope mount is attached is often called the base or rail Some types of bases are Standard mounts Picatinny rail Standardized slot distances Weaver rail Varying width between the slots nbsp Metric dimensions

standardized even for a given witdth Trijicon ACOG VCOG rail nbsp HK MSG90 with a scope sight mounted in a STANAG claw mount Screw pattern on bases edit On receivers without an integrated attachment for mounting a scope for example an integrated Picatinny rail the base is usually screwed on as a separate part Such mounts are often model specific to the firearm and depend on factors such as the radius of the receiver bridge the type of screw and the distance between the screw holes A common fastening method is by screws These are often metric M3 5x0 6 mm or US 6 48 3 5 mm 0 53 mm pitch or 8 40 4 2 mm 0 64 mm pitch Many European assemblies use M3 5 screws such as SAKO Optilock Recknagel and original CZ rings Since 6 48 and M3 5x0 6 have near identical diameters and almost equal pitch there is a potential for confusion and upon mixing the wrong screw will enter the threads but will gradually become tighter to screw until the thread is destroyed In case of damage the hole must often be drilled and re threaded and M4x0 7 or 8 40 may then be relevant alternatives Remington 700 pattern The Remington 700 Short Action SA scope base attachment pattern is particularly widespread and is for example used on models such as 54 Remington Model 722 40x 78 740 742 760 710 721 722 and 725 Mauser M1996 straight pull and Roesser Titan 16 Mauser SR 97 Sauer 100 Sauer 101 Mauser M18 not the M12 Bergara B14 LA Haenel Jager 10 Sabatti Rover LA The Remington 700 Long Action LA naturally has a longer distance between the front and rear screw holes and therefore continuous scope mount assemblies for the 700 LA do not fit on the 700 SA nor the above mentioned firearms However two piece scope mounts in general interchange for the mentioned models List of common screw patterns Bases with a rounded bottom for mounting on a round receiver bridges should ideally have a slightly smaller radius than the receiver in order to provide two points of contact and give a stable attachment Conversely a slightly too large radius on the mount will result in just one point of contact and a less stable attachment In the table below the radius refers to the curvature of the mounting surface on the receiver bridge The base is often attached with two screws on the front receiver bridge and two screws on the rear receiver bridge but sometimes with several more screws The hole distances are measured from center to center Some common hole distances are 12 7 15 37 and 21 84 mm 0 500 0 605 and 0 860 in respectively 55 The two front screws are referred to in the list below as screws 1 and 2

Main article Milliradian Adjustment range and base tilt In some cases it may be relevant to add extra inclination to the scope to be able to shoot at longer or shorter distance For example this is popular for long range shooting where it is common to use a tilt of 6 mrad 20 MOA Extra tilt can be achieved several ways like for example with a tilted Picatiny rail e g 6 mrad tilt with bases or rings e g 6 mrad tilt or with special insert rings e g Burris Pos Align 21 Scope height editThe height of scope sight can be important for the cheek rest support often called cheek weld to gain correct eye placement as well as for calculating ballistics e g a ballistic table The latter is particularly relevant at very close ranges e g 15 meters 49 feet while at longer distances such as in long range shooting the scope height has less impact on the ballistic calculations The height of a scope sight can be measured in many ways With regard to ballistic calculations it is generally only measured from the center of the bore axis to the center of the scope sight sightline With regard to cheek support several methods are used On firearms with a picatinny rail the height is measured from the top of the picatinny rail on the firearm On most other types of bases it is common to measure from the top radius of the receiver bridge When the bottom measuring point is determined the height is then measured up to either the optical center or the bottom of the scope tube on scopes for ring mounts The difference between these two measuring methods is distance from the optical center to the bottom of the scope tube and usually corresponds to half of the tube diameter e g 15 mm on binoculars with a 30 mm tube See also editM LOK BipodReferences edit Blaser Infinity 2 8 20x50 IC vs
