ALWAYS ARMED 5.5" 9MM STAINLESS STEEL TR SERIES UPPER RECEIVER WITH 4" RAIL - BLACK

Build an ultra-compact, fast-cycling pistol caliber carbine with the Always Armed 5.5" 9mm SS TR Series Upper Receiver. Precision-engineered and 100% Made in the USA, this micro AR-9 assembly combines target-grade 416R stainless steel performance with a durable Type III Hard Coat Black Anodized finish.

Built on a forged Mil-Spec AR-15 aluminum upper receiver, this unit features a 5.5" 416R stainless steel barrel with a 1:10 twist rate. Chambered in 9x19mm Parabellum, the 416R stainless steel construction ensures superior corrosion resistance, extended barrel life, and exceptional accuracy for personal defense or target shooting.

The barrel is housed under a compact 4" TR Series Free-Float M-LOK Handguard, offering a top Picatinny rail for red dot optics alongside modular M-LOK slots for hand stops and accessories. A specialized Flash Can muzzle device extends forward to push blast, noise, and gases directly away from the shooter. (Note: Bolt Carrier Group and Charging Handle sold separately).
