AR-9 80% Lower Receiver, Billet 9mm – Fire/Safe Marked

You’re building an AR-9. You want it tough, precise, and built to run. This is the 80% lower that gets you there. Machined right here in the USA from a solid block of 6061-T6 billet aluminum, this isn’t a flimsy forging. We cut it on CNC machines for a tight, clean fit with your upper receiver. The finish is a proper Type III hardcoat anodize. It’s not just for looks; it’s armor against wear and corrosion.

The mag well is flared and ramped. This isn’t a minor detail—it means positive, quick magazine insertion every time, especially when it counts. It’s built for reliability with your GLOCK® OEM or ETS magazines, so you’re running a proven, common mag system.

We’ve included the Fire and Safe engravings. It’s one less step for you. The trigger guard is integrated, so it’s part of the lower itself. No pins to lose, no weak points.

This is a 100% mil-spec footprint lower. Every standard AR-9 parts kit and jig will fit it. You’re getting a professional-grade blank to finish yourself, with the quality that respects the work you’re going to put into it.
