Description

The Sig Sauer Alpha MSR Scope Mount delivers precision mounting for 30mm riflescopes on AR-15 and MSR platforms. This black anodized aluminum mount system combines rings and base in one unit, eliminating alignment issues common with separate ring systems.

What Makes This Different

Unlike traditional two-piece ring systems, the Alpha MSR features an integrated cantilever design that positions the scope at optimal eye relief for modern sporting rifles. The single-piece construction eliminates ring-to-base misalignment while providing consistent return-to-zero performance. Machined from 6061-T6 aluminum with Type III hard anodizing, this mount withstands recoil forces up to .308 Winchester without shifting.

Key Features

30mm tube diameter accommodates popular tactical and hunting optics
1913 Picatinny rail interface fits AR-15, AR-10, and MSR platforms
Cantilever design extends scope forward for proper eye relief positioning
6061-T6 aluminum construction with Type III hard anodized finish
Integrated ring and base design eliminates alignment variables
Cross-bolt ring caps provide secure optic retention
Low-profile design maintains sight line clearance

Field testing demonstrates consistent point-of-impact retention through temperature cycles and repeated mounting. The mount handles rapid-fire strings without thermal expansion issues affecting zero. Competition shooters report maintained accuracy through 500+ round sessions, while hunters appreciate the lightweight profile that doesn't affect rifle balance. The hard anodized surface resists wear from tactical slings and bipod contact.
