Introducing the Spuhr ISMS Cantilever SP-3026 “The Noveske Team mount”, with most AR15 style cantilever mounts being 1.5″ (38mm) high which provides a nice good cheek weld. However the Spuhr ISMS SP-3026 is 1,25″ (32mm high) which gives a much tighter cheek weld than most other AR-mounts on the market, making fast and instinctive shooting much easier and faster.
The Spuhr ISMS Cantilever SP=3026 mount is designed for speed shooting in 3 gun and IPSC-style rifle competitions and therefore does not have the bubble level most other Spuhr mounts have.
The Noveske Team mount was developed on special request from the Noveske Shooting Team to give them extra advantage in 3 gun competitions.
Genereal Information about Spuhr ISMS Mounts
The Spuhr ISMS Cantilever scope mounts are designed to fit directly onto your picatinny rail or directly to your rifles receiver. This Spuhr ISMS Mount System is designed to fit to your Picatinny rail. The Spuhr ISMS Cantilever scope mount is one of the best in the world and is available in 30mm, 34mm, 35mm, 36mm and 40mm.
The Spuhr ISMS (Ideal Scope Mounting System) is an extremely sturdy scope mount that is machined from one piece solid billet, in 7075 T651 aluminium with no joins or joints which that can become weak overtime. This completely unique lightweight design of the Spuhr ISMS Cantilever mount provides the platform for a rock solid picatinny style mounting system that will allow you to easily mount accessories and keep clear visibility of the scope turrets with minimal movement. This feature packed mount system from Spuhr really does make it the Ideal Scope Mounting System. A Built-in level is also found in the base of the one piece mount and a 45-degree split of the rings provides unobstructed view of the turret knobs.
- 10-degree leveling wedge
- -This simple tool fits in a 10-degree slot on the mount while mounting the scope and works against the bottom of the scope to ensure a perfectly level scope.
- 4 numbered and indexed mounting torx heads
- Built in level
- -Even the slightest variance in how the mount is attached to a weapon can alter the point of impact. To resolve this, the ISMS has numbered screw holes so you can attach the mount the same way each time. The amount of torque applied to the mount can also cause unwanted variance so Spuhr has placed index marks on the screw head so you can put the exact same amount of torque on your mount no matter how often you remove the mount.
- -With a quick glance from your left eye you can get an instant check of your level without leaving your shooting position. The built in level is always protected in the rear of the mount and is not a risk of shifting or being broken off on the move.
- Accessory interface :
- Every mount consist of 7-8 mounting interfaces where you can attach nearly anything. The interface consists of two threaded M4 holes that are depressed in a conical hole to perfectly fit the individual attachment interfaces (sold separately) with absolutely no play in the joint.
A Spuhr ISMS Cantilever Mount System will prevent damage on a 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.
Spuhr ISMS Mount System has an 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.
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. Spuhr ISMS Cantilever mounting systems 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.
Spuhr ISMS Mounts can be delivered in various tilts. The tilt is clearly engraved on the mount, in both MIL and MOA.
Accessible and readable dials
Spuhr ISMS Cantilever 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. The Spuhr ISMS also gives the shooter a horizontal reference line helping the shooter sub-consciously 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.
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.
The sight mount have a level included in the rear of the mount.

HOW TO CHOOSE THE RIGHT SPUHR ISMS MOUNT
We have the worlds most comprehensive line of tactical scope mounts; it currently spans about 45 different models of various heights, tilts, lenghts and ring dimensions.
Here is a short guide to help you choose the right one for your needs.
Picatinny or direct mount?
The first obvious question is if the mount should be a Picatinny mount or a direct attachment mount such as our line of ISMS mounts for Accuracy International, Sako TRG and Sauer SSG.
The main purpose for using a direct mount is to allow a stronger and lower positioning of the rifle scope. If there’s no need for Picatinny we generally recommend direct mounts on these rifles.
Tilted mounts are necessary when shooting at very long distances. We generally recommend as little tilt as possible as the tilt really does nothing to improve the picture quality. In most cases 6-9 MIL (20-30 MOA) will have no negative impact on picture quality while a greater tilt can
lead to problems.
To allow for the greatest available range of adjustment choose a mount with a tilt that is half of the scope’s range of elevation.
For example Schmidt & Bender 5-25×56 have a maximum 26 MIL (93 MOA) in elevation, then choose amount with 13 MIL (45 MOA) in tilt. Doing so assures that you are able to adjust the sight out to very long distances.
However when mounted in this extreme elevation it’s common to experience optical defects such as anoval picture etc.
We therefore recommend that when fitting a large elevation scope (such as 26 MIL/93 MOA) on a .308 rifle that will only be used out to 1000 meters, to choose a 6 MIL/20 MOA tilt as it’s more than sufficient for that use.
The height of a mount is always measured from the top of the rail to the center of the scope. In the case of a tilted mount the measurement is made at the rear of the mount.
Night vision/thermal compatible
When combining the scope with a clip-on system such as PVS22 or NSV 80 to name a few the height of the mount is not important. Also the instrument doesn’t have to be perfectlyin line with the scope.
If we have an offset of 10mm in height betwen the primary optic and the NV clip-on the change in point of impact will be 10 mm on 100 meters as well as 10 mm on 300 and 1000 meters; thus the point of impact change is fully parallell.
Therefore it’s often unneccesary to have extremely high mounts just to facilitate in-line mounting of a clip-on systems. Various systems allow varying degrees of angular difference. A common maximum angular difference is 2 degrees.
Please consult the manufacturer of the thermal device before you make expensive alterations to your gear.
