The Sig Sauer Alpha-MSR Scope Mount (brand part no. SOA20017) is a one-piece, 0 MOA integral mount machined from 7075-T6 aluminum to clamp a 34mm riflescope directly to an M1913 Picatinny rail. An epoxy powder coat finish resists oxidation, gun oils, cleaning solvents, and outdoor exposure, keeping the mount protected through hard use. The clamp grips the rail while precise machining keeps the ring bore true to the scope tube, avoiding the pressure points that can damage glass under improper installation. SIG specifies 65 in-lb of torque on the rail nut and 25 in-lb on the T15 Torx scope screws, and the mount is covered by SIG Sauer’s Infinite Guarantee. This model ships in a coyote finish.
