SIG SAUER ALPHA MSR 30mm Coyote Scope Mount

Description

SIG SAUER ALPHA MSR 30mm Coyote Scope Mount

The SIG SAUER ALPHA MSR 30mm Scope Mount is a one-piece cantilever mounting solution for riflescopes with a 30mm main tube. Designed for M1913 Picatinny rails, this SOA20016 configuration combines a coyote finish, 1.535-inch optical height and 0 MOA cant. Its forward-offset layout helps position an optic for proper eye relief on modern sporting rifles while keeping the complete mount secured to the receiver rail.

Precision-machined 7075-T6 construction gives the mount a strong, rigid foundation. Steel M1913-style clamps form the rail interface, and the ring assembly is engineered to wrap evenly around the riflescope tube when installed to specification. Epoxy powder coating on the steel components helps protect against oxidation and exposure to gun oils, cleaning products and field conditions.

Integrated alignment and useful offset

Because both rings are part of a common base, an integral mount maintains their alignment and removes the need to position two separate rings independently. The cantilever extends the optic forward, creating additional flexibility for establishing eye relief and a repeatable head position. A 1.535-inch centerline height works well with the straight-line stocks found on many AR-pattern and similar Picatinny-equipped rifles.

This model has a 0 MOA cant, meaning the mount does not add a built-in downward inclination to the optic. That neutral orientation is appropriate for many general-purpose and low-power variable optics. Always confirm the required height, available rail space and eye-relief range for the exact rifle and scope before beginning installation.

Install with controlled torque

SIG SAUER lists a torque specification of 65 inch-pounds for the mount’s 1/2-inch rail nut and 25 inch-pounds for the T15 Torx scope fasteners. A calibrated torque driver should be used so the mount remains secure without crushing or distorting the optic tube. Tighten the ring fasteners gradually and evenly, following the manufacturer’s installation guidance.

Before assembly, unload the firearm and clean the rail, clamp surfaces and ring interiors. Seat the mount fully in the chosen Picatinny slot, set eye relief, level the reticle and then apply the specified torque. Inspect the mount after the initial range session and periodically thereafter, especially following hard use or transport.

Verify tube diameter before ordering

This ALPHA MSR model fits 30mm scope tubes. It will not correctly secure a one-inch or 34mm optic, even if the mounts appear similar in photographs. Confirm the scope’s published maintube diameter and verify that the rifle has a properly dimensioned M1913 Picatinny rail. With the correct optic and careful installation, the SIG SAUER ALPHA MSR offers a durable, aligned mounting platform for a broad range of modern rifle applications.
