The Battle Arms Development Xiphos billet lower receiver (part no. XIPHOS-LR) is machined for a 9mm AR pistol-caliber carbine build designed to run Glock-pattern magazines, giving builders a purpose-cut receiver instead of adapting a standard AR-15 lower. Sold stripped, it ships with no internal fire-control parts installed, so you choose the trigger, safety, and furniture for your 9mm build. It is built for shooters who want a dedicated Glock-magazine-compatible AR platform from a well-known billet manufacturer.
