BM-9 Completed Lower 9mm:

The Brigade MFG BM-9 Complete Lower Receiver is built for AR-9 direct blowback platforms and accepts Glock 17 or 19 style magazines, allowing seamless magazine interchange between your AR-9 and compatible Glock handguns. It features a Last Round Bolt Hold Open (LRBHO) system that locks the bolt back after the final round, enabling faster reloads and giving you a tactical advantage. CNC machined from 7075-T6 aluminum, the BM-9 lower is based on a MIL-SPEC platform, ensuring long-term serviceability and compatibility with standard MIL-SPEC upper receivers, streamlining the process for your complete build.
