Sig Sauer Electro-Optics Soa20017 Alpha Msr Coyote Brown Aluminum 34Mm Tube, Picatinny Rail Mount

The Sig Sauer Alpha MSR scope mount in coyote brown is a precision-engineered ring system built to secure 34mm rifle scopes solidly to any Picatinny rail without compromise. Machined from 7075-T6 aluminum, this mount delivers the rigidity hunters and precision shooters need for reliable zero retention, whether you're building a long-range hunting rig, tactical carbine, or dedicated range gun. Sig's proprietary design balances strength with a controlled grip that seats your scope safely—no marring, no slipping.

The coyote brown finish works as hard as you do: it's epoxy powder coated to shrug off gun oils, solvents, sweat, and the elements. The steel 1913-style clamps lock onto standard Picatinny rails with confidence, and the integral mount design means no extra hardware or adapters cluttering your rail real estate. Set it once with the correct torque specs, and this mount will hold zero through whatever conditions you throw at it.

Sig backs this mount with their Infinite Guarantee—peace of mind that you've bought a piece of gear built to last. If you're upgrading an AR, precision rifle, or any platform with a pic rail and a 34mm scope tube, the Alpha MSR delivers the kind of repeatable, field-proven performance that separates good gear from great.

Frequently Asked Questions

What size scope tube does this mount fit?

The Alpha MSR is designed for 34mm scope tubes. Do not use with 30mm or 1-inch tubes.

What rail systems is this compatible with?

This mount uses M1913 (Picatinny) clamps and will fit any standard Picatinny rail found on AR-15s, precision rifles, and most modern tactical platforms.

What tools and torque values do I need for installation?

You'll need a T15 TORX driver for scope ring installation (torque to 25 in/lbs) and a 1/2-inch wrench or socket for rail attachment (torque to 65 in/lbs). Always use the correct torque values to avoid damaging your optic.

Does this mount come with rings or a separate scope tube clamp?

The Alpha MSR is an integral mount system—the clamps are built into the body. No additional rings are required for 34mm scopes.
