RECEIVER SET:

Our in house machined AR9 billet lower/upper receivers are machined from a solid brick of 7075-T6 aluminum to provide a higher quality tier over 6061-T6. All of the critical features and dimensions are cut in a single operation, ensuring that every receiver is perfectly in spec. We then broach the magazine well for a perfect magazine fit, hand deburr, and tumble before coating. These receivers have an integrated magazine release. The receiver bolt catch holes are threaded, eliminating the standard roll pin. The rear detent is also retained by a threaded cap screw making maintenance a breeze.

Our billet uppers are also made from 7075-T6 aluminum and are matched with the lower. Dedicated PCC design to cut weight and streamline the functionality of the pistol caliber carbine.
