The Brownells BRN-9 Upper Receiver 9MM is a marvel of engineering, designed for AR-15 pistol and pistol-caliber AR enthusiasts. Crafted from a single billet of aluminum, it features a blowback-operated system that does not require the AR-15 recoil buffer system, allowing for a folding stock. The 5.5-inch nitrided barrel with 1/2"-28 threads is perfect for 9mm ballistics, offering superior control and accuracy.

Ideal for range time and competitive shooting, the BRN-9 pairs well with a variety of 9mm magwell adapters and lower receivers. Brownells is renowned for its innovation and quality in firearm accessories.
