Sig's proprietary alloy ALPHA2 Scope Mounts are machined with an exactness that is both strong yet ductile that allows their rings to form around a riflescope, yet will not damage the scope under proper installation. The rings are epoxy powder coated to prevent oxidation and resist gun oils, cleaning solutions, and outdoor exposure.

with 34mm ring diameter and a slightly extended body, this scope mount will fit a large variety of scopes and fit nicely with an AR platform that needs a little extension over the receiver for proper eye relief.  The 0 MOA cant makes it ideal for short to medium distance optics
