Brownells is proud to unveil the BRN-180® GEN3 upper receiver, the latest evolution of the groundbreaking BRN-180 series. Built on the feedback of passionate BRN-180 users and backed by extensive in-house testing, the GEN3 offers cutting-edge upgrades to enhance ergonomics, adaptability, and reliability—all while preserving the core features that made the BRN-180 a standout.
Refining a Classic:
The BRN-180 GEN3 maintains the proven short-stroke gas piston system inspired by the iconic AR-180 and remains buffer-tube-free for unparalleled compatibility. Its rugged design ensures it is drop-in ready for standard mil-spec AR-15 lowers or lowers specifically designed for Picatinny-mounted stocks. These foundational elements, combined with innovations, make the GEN3 a perfect addition for new and loyal BRN-180 owners.
Key Features & Upgrades of the BRN-180 GEN3:
Non-Reciprocating Left-Side Charging Handle: This is now situated on the left side of the receiver to prevent interference with the shooter’s hand during cycling. While the redesigned charging handle allows for better ergonomics.
Redesigned, Easy-Adjust Gas System: Enables rapid adjustments for suppressed and unsuppressed shooting scenarios. Simply reach through the opening in the handguard to flip the lever between the Suppressed, Normal, and Adverse gas settings.
“Automatic” Ejection Port Cover: This design attaches the cover to the bolt-carrier assembly, sealing the ejection port when the bolt is forward, providing protection against dust and debris without manual manipulation.
Rubber Dust Cover: It is sealed with a special Swiss-inspired rubber gasket that lets the handle move freely while keeping foreign matter out.
Anti-bounce Bolt Carrier: The geometry was designed to prevent light primer strikes, improving reliability in all conditions.
From improved ergonomics to extended service life, the BRN-180 GEN3 is the pinnacle of Brownells’ commitment to innovation and performance. Whether you’re a first-time buyer or adding to your collection, this upper receiver delivers a robust, reliable platform that exceeds expectations.
