Extremely sturdy scope mount, with possibility to attach multiple optical accessories directly to the mount. Built-in level. 45-degree split of the rings provides unobstructed view of the knobs.
Durability
Prevents damage on scope due to flexing during heavy recoil or rough handling. The snipers rifle and the spotter’s carbine can have the same mount, enabling the use of the same or shared equipment and accessories.
Scope rotation
Innovative solution for indexing the rotation of the scope, using the included tool/gauge to index the scope correctly to the mount and gun. This is very important since if the scope is not properly indexed there will be an unintended lateral shift of the point of impact whenever the elevation is adjusted.
Mounting placements
Traditionally lasers have been mounted on the forend of the rifle, a solution with drawbacks. For the same reasons you don’t want your barrel to touch the forend you don ́t want the sights to be mounted on the forend. Our mounting system have up to seven interfaces for accessories, and the laser can easily be attached to the scope mount, providing the advantage of undisturbed laser and having the weight close to the centre of the gun instead of forward.
Tilt
Mounts can be delivered in various tilts. The tilt is clearly engraved on the mount, in both MIL and MOA.
Accessible and readable dials
The rings are cut at 45 degrees instead of horizontaly, providing several advantages; the screws holding the parts together are not obscuring the knobs, thus the shooter can quickly determine the settings of the knobs.It also gives the shooter a horizontal reference line helping the shooter subconsciously to avoid canting the rifle to the side.
The rings have index marks on the top and right side, making low knobs more easily readable.
Accessories
Provides use of various accessories such as angle cosine indicator (ACI), back up sights, lasers, illuminators, night vision mounts etc. with a minimized ”footprint”. With traditional mounts this can only be achieved if there is sufficient space on the middle tube for additional rings, which there rarely is. The ”Ideal Scope Mount System”™ have interface surfaces directly on the mount, making it possible to mount accessories either by Picatinny rails or as direct interfaces. A selection of interfaces for popular accessories are available, and others can be made to customer specifications.
Level
The sight mount have a level included in the rear of the mount.
The initial letters identify the type/firearm/rail the mount is designed for:
QDP - Quick Detachable mount Picatinny
SA - Scope mount Accuracy International (11mm dovetail)
SP - Scope mount Picatinny
SS - Scope mount Sauer (for Sauer SSG and STR rifles)
ST - Scope mount TRG (17 mm dovetail)
SR - Scope Rings (separate rings for Picatinny rail)
The first digit identifies tube diameter:
3 - 30 mm tube
4 - 34 mm tube
5 - 35 mm tube
6 - 36 mm tube
7 - 40 mm tube
The second digit identifies tilt:
0 - 0 tilt
3 - 3 MIL/10.3 MOA
6 - 6 MIL/20.6 MOA
7 - 7 MIL/24 MOA tilt
8 - 13 MIL/44.4 MOA
9 - 9 MIL/31 MOA
Note: The SP-61602 and SP-41808 feature two digits for tilt: 16, indicating a tilt of 16 MIL/55 MOA, and 18, indicating 18 MIL/61.8 MOA. First run of SP-4803b had 11 MIL/40 MOA tilt.
The third digit (if other than 0) is for special versions:
1 - Cantilever mount
2 - Extended cantilever mount
3 - Short rear top cover for the S&B Ultra Short
4 - Medium cantilever mount
The fourth digit identifies height:
1 - 30 mm / 1.18"
2 - 38 mm / 1.50"
4 - 48 mm / 1.89"
6 - 34 mm / 1.35" (except for on Cantilever mounts)
8 - 44 mm / 1.73"
Note: The height is always measured from the top of the rail to the centerline of the optics. On a tilted mount the measurement is made at the back plane of the rear ring.
B suffix
Some mounts feature a B suffix following the model number. In the ISMS line this indicates an extra-long mount for scopes with extended length erector housings, such as the U.S. Optics TPAL and the NightForce B.E.A.S.T.
Cantilever Mounts
We currently offer three heights for our cantilever mounts. The high cantilever mounts (where the third digit is a 1) are 38 mm / 1.5" high,
the medium cantilever mounts (where the third digit is a 4 - currently only available as as QDP) are 36 mm/1.35" high, and the extended cantilever mounts (where the third digit is a 2) are 32 mm / 1,26" high.
