The ISMS (Ideal Scope Mount System) is an extremely sturdy scope mount, with the possibility to attach multiple optical accessories directly to the mount. Built-in scope level and 45-degree split of the rings provides unobstructed view of your optics knobs. The durable design of the mounts prevents damage to the scope due to flexing during heavy recoil. The rings are grooved on the inside for better grip and the mount base is milled from a sinlge billet of aluminum.
Mounts include an innovative tool to index your scope properly to the mount and gun. Mounts have a minimum of 7 interfaces for accessories to be mounted. The rings are cut at a 45 degree angle instead of horizontally, providing several advantages; the screws holding the parts together are not obscuring the optics knobs, it gives the shooter a horizontal reference line helping the shooter avoid canting the rifle. Mount level is built into the bottom rear of the mount enabling the shooter a quick, accurate means to insure he avoids canting the rifle.
