The Sig Sauer Alpha3 SOA30006 scope mount delivers precision rifle accuracy with its integrated 20 MOA cant and robust 30mm ring design. This single-piece mount eliminates alignment issues while providing the elevation advantage needed for extended range shooting. Built from aircraft-grade aluminum with Type III hard anodizing, it maintains zero under heavy recoil and extreme conditions.
What Makes This Different
Unlike traditional two-piece mounts that can shift under recoil, the Alpha3 features a monolithic construction that spans multiple Picatinny rail slots for maximum stability. The built-in 20 MOA forward cant extends effective range by 200-300 yards compared to standard 0 MOA mounts. Four large cross-bolts per ring create 40% more clamping surface than competing designs, preventing scope slippage during rapid fire or magnum cartridge use.
Key Features
- Integrated 20 MOA cant extends long-range capability without scope adjustment limits
- 30mm tube diameter accommodates premium tactical and hunting optics
- Single-piece aluminum construction eliminates ring-to-base alignment issues
- Type III hard anodized finish resists corrosion and wear
- Four cross-bolts per ring with 25 inch-pounds torque specification
- Compatible with MIL-STD-1913 Picatinny and Weaver-style rails
- Low-profile design maintains proper cheek weld and sight picture
Field testing shows the Alpha3 maintains sub-MOA zero retention through 500+ rounds of .308 Winchester and magnum cartridges. The 20 MOA cant allows shooters to engage targets beyond 800 yards without maxing out scope elevation adjustments. Weather sealing at all contact points prevents moisture intrusion during extended outdoor use. Competition shooters and tactical professionals rely on this mount for matches and duty applications where equipment failure isn't acceptable.
