The Spuhr ISMS (Ideal Scope Mounting System) is machined from one-piece solid billet, in 7075 T651 Aluminum with no joints or that can over time become a weakness in a mount. The unique lightweight design of the Spuhr mount provides a rock solid Picatinny-style mounting platform that lends itself to easy accessory mounting and clear visibility of the turrets with minimal movement. The lengthy list of features that Spuhr has packed into one mount makes it the truly Ideal Scope Mounting System.
- 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
-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.
- Built in level
-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.
