Spuhr Cantilever Scope Mount


Considered by many as the ”only way” to mount long long range optics, Spuhr Mounts have been carefully developed from original drawings all the way through to production, with the aim of creating a product that secures your optics with zero movement and also allows the shooter easy access to the turrets. In fact the Ideal Scope Mount System (ISMS) has been developed so that the shooter can read the turret markings with minimal movement from the shooting position.

Absolute co-witness most clip-on NV units on AR platforms. Allows the scope to be mounted 40 mm/1.57” or extended 70 mm/2.76” farther forward than with a non-cantilever mount.

Scope mounts are marked with a model number consisting of two or three letters followed by four digits, for example SP-4901.

The initial letters identify the type/firearm/rail the mount is designed for.
The first digit identifies tube diameter.
The second digit identifies tilt.

Machined from 7075 T651 billet aluminum for the majority of the mounts – the Spuhr product is guaranteed to be lightweight and extremely strong, to the point where the materials outperforms construction steel in many tests.

Installation has also been considered as part of the design process. At the rear of most Spuhr mounts there is spirit level for perfecting alignment and in the box is a 10-degree “wedge” to helps the user align the erector housing of the optic to the bridge of the mount.


Prevents damage on scope due to flexing during heavy recoil or rough environment. The snipers rifle and the spotters carbine can have the same mount, enabling the use of same equipment and accessories. Rings are grooved inside to get a better grip of the scope and enabling gluing of the scope. The mount is milled out of one billet of material instead of being screwed together from small parts.

Scope Rotation

Patent pending solution for indexing the rotation of the scope, using an included tool/gauge to index the scope correctly to the mount and gun. Important since an incorrectly indexed scope unintentionally will also have a sideways adjusted point of impact and since it will be adjusted sideways when it is adjusted for elevation.

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 has a minimum of seven interfaces for accessories and the laser can easily be mounted on the mount, giving the advantage of an undisturbed laser and a weight more central on the gun instead of forward.

Accessible and Readable Dials

The rings are cut 45 degrees instead of the usual horizontal, providing several advantages. The screws holding the parts together are not in the way of the knobs, thus the shooter can quickly determine the settings of the knobs. It also gives the shooter a horizontal line that helps the shooter not torotate his gun unintentionally. The rings have index marks on the top and right side, making low knobs more easily readable.


Possibility of using various accessories such as angle cosine indicator, back up sights, lasers, illuminators, Night vision mounts etc. With traditional mounts this can be achieved only if there is sufficient space on the middle tube for additional rings, which there rarely is. Ideal Scope Mount Systems have interface surfaces directly on the mount, making it possible to mount accessories either by Picatinny rails or as direct interfaces for certain accessories such as angle cosine indicators and red dot sights. A selection of interfaces for popular accessories are available, and others can be made to specification.
