Weighs in at a mere 6 ounces!
Crafted from 6061 Aircraft Grade Aluminum. At a weight comparable to a set of lightweight rings, it provides the added rigidity and convenience of a one piece mount.

Built specifically for 1 inch scopes.
The mount is built for standard 1 inch tube scopes for mounting to any standard Picatinny rail equipped rifle.

Square Integral Recoil Stops
This scope mount also features 4 square-integral recoil stops, which allows us to shave down the weight, while increasing the strength.
