Key Features

• CNC-milled handguard that is Type III hard-coat anodized aluminum for maximum durability, with Magpul M-LOK accessory attachment slots on all four sides for easy mounting of M-LOK-compatible rails and accessories.

FAQ

Do I need ATF approval to buy this?

Yes. This is a short-barreled rifle under the NFA, so it transfers on an approved ATF Form 4 and goes through background checks just like a suppressor. The $200 tax stamp for SBRs was cut to $0 starting January 1, 2026, but the Form 4 approval is still required. Call the store and we’ll walk you through the process.

Is the barrel threaded?

Yes. The muzzle is threaded 1/2″-28 and ships with a thread protector, so it’s ready for a suppressor or muzzle device.

What magazines does it use?

It ships with the Ruger SR-Series / Security-9 magazine well installed and a second well that takes Glock 9mm magazines. One 17-round magazine is included.
