Sig Sauer Alpha 1 35mm Medium Scope Mount - 0 MOA Matte Black

The Sig Sauer Alpha 1 35mm scope mount delivers precision rifle optic mounting with zero MOA cant for shooters demanding repeatable accuracy. This medium-height mount accommodates 35mm main tubes while maintaining proper scope-to-rifle alignment across multiple shooting positions.

What Makes This Different

The Alpha 1 mount system utilizes a split-ring design with four cap screws per ring, distributing clamping force evenly around the scope tube to prevent optical distortion. Unlike traditional two-piece mounts that can introduce stress points, this integrated rail system maintains consistent torque specifications across the entire mounting platform. The 0 MOA configuration ensures the scope's internal adjustment range remains centered for maximum elevation and windage travel.

Key Features

• 35mm tube diameter compatibility with medium height clearance
• Matte black hard-anodized aluminum construction resists corrosion
• Zero MOA cant maintains scope's full adjustment range
• Split-ring design with four cap screws per ring for even pressure distribution
• Picatinny rail interface with recoil lugs for secure attachment
• Precision-machined surfaces ensure repeatable return to zero
• Compatible with standard 35mm riflescopes from major manufacturers

Field performance testing shows the Alpha 1 mount maintains zero through temperature cycling from -20°F to 120°F. The medium height provides adequate clearance for standard objective lenses up to 50mm while allowing proper cheek weld on most rifle stocks. Competitive shooters report consistent point of impact after scope removal and reinstallation, critical for match rifles requiring frequent transport.
