The BM-9 9.5" Complete Upper Receiver delivers maximum velocity, superior accuracy, and enhanced control for your AR-9 build. Engineered with a proprietary ramped feed ramp to solve standard PCC feeding issues, it reliably cycles defensive hollow points and flat-point ammunition out of the box.
Standard AR-9 upper assemblies often struggle with hollow-point ammunition. The BM-9 features an engineered ramped barrel extension designed to feed hollow points and flat-point defensive rounds flawlessly.
No extra sourcing required. Every BM-9 upper comes fully assembled with a direct blowback AR-9 Bolt Carrier Group (BCG), charging handle, and factory-installed Mini Can muzzle device.
The 8-inch free-float U-LOK handguard offers absolute mounting versatility. Attach both M-LOK and KeyMod accessories without needing adapters or changing handguards.
CNC machined from MIL-SPEC 7075-T6 aluminum forgings and paired with a 416R stainless steel barrel for extreme durability under rapid fire. Finished in ceramic Cerakote.
