BRN-180 GEN 2 SPORT COMPLETE UPPER RECEIVER ASSEMBLY
The core operating system of the popular BRN-180™ with new straight charging handle, fits standard AR-15 lower receivers.
Based on the 16” BRN-180™ Gen2, the BRN-180™ Sport foregoes the ejection port cover allowing for the use of a straight charging. This arrangement allows for a slimmer profile on the ejection port cover side and avoids interference with wide optic mounts and accessories. The charging handle location is also lower, making it faster to actuate with the firing hand of right-hand shooters.
Operating system of the BRN-180™ Sport is unchanged from the Gen2 models, with a reliable short stroke gas piston that can be easily maintenance with removal of the handguard. The gas system is also adjustable, with two settings, ensuring you can select the softest shooting setting. Handguard is retained with a single screw at the bottom, near the trunnion. Loosening the screw allows the free float handguard to be slid forward. MLOK slots surround the handguard, allowing attachment of various accessories. Monolithic like upper & handguard fitment ensures a consistent top Picatinny rail to align optics.
