About the Brn 180 GEN3 Upper

The Brownells BRN-180 Gen3 upper receiver is a self-contained piston-driven upper designed for AR-15 lower receivers. It offers a different operating system than the standard direct impingement AR-15. This particular model is chambered in .223 Wylde, which can safely fire both .223 Remington and 5.56x45mm NATO ammunition. It features a 13.9 inch barrel, providing a compact rifle or pistol build when paired with an appropriate lower receiver. This item is noted as a blemished product, indicating minor cosmetic imperfections.
