Description

The Sig Sauer ALPHA-MSR is a one-piece scope mount for modern sporting rifles. Both rings are part of a single base, so there is no separate base and ring set to line up. This configuration holds riflescopes with a 34mm main tube and has a 1.535 inch mount height, a common choice for flat-top AR-pattern rifles where the scope has to sit high enough for a natural head position.

The mount clamps to an M1913 Picatinny rail using steel 1913-style clamps, and Sig lists the body material as 7075-T6 with 0 MOA of cant. Sig publishes torque values of 65 in/lbs for the 1/2 inch rail nuts and 25 in/lbs for the T15 Torx ring screws, which makes installation repeatable with a torque wrench. The mount is covered by Sig Sauer's Infinite Guarantee.

This is the coyote 34mm version, intended for shooters who want the mount to match a coyote or tan rifle or optic. Sig also offers the ALPHA-MSR in black and for 30mm tubes, and those are separate part numbers that are not interchangeable with this one. Match the mount to your scope's main tube diameter first, then confirm that a 1.535 inch centerline height suits your setup.
