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.
