AR9 80% Lower Fire/Safe Marked – 9mm – Billet

This AR9 80% lower is cut from 6061-T6 billet aluminum with tight CNC tolerances, built specifically for 9mm PCC builds that take Glock mags. The Type III hardcoat anodizing holds up to heavy use, and the flared magwell speeds up reloads when you’re running drills. It’s fire/safe marked right out of the box, saving you a trip to the engraver.

The lower maintains mil-spec dimensions where it counts, so it pairs with standard AR triggers and pistol braces. The enlarged feed ramps help with reliability when you’re dumping mags. Works with OEM Glock mags and most aftermarket options – no adapters needed.

Good for builders who want a dedicated 9mm lower without modifying a standard AR-15 receiver.
