SIG SAUER Infinite Guarantee
The SIG SAUER ALPHA3 Scope Mount is a proprietary aluminum-alloy, one-piece mount machined to grip your riflescope securely without marring it under proper installation. The rings are anodized for protection and durability against the elements, while the 1913-style clamps and 1/2-inch lock nuts hold the mount firmly to a Picatinny rail, and the four-screw ring design keeps your optic from moving under recoil for repeatable accuracy in the field.
This configuration features a 30mm ring, 1.375-inch height (optic centerline to rail) and a 0-MOA cant.
