BRN-180S"! GEN2 13.9/14.5 223/5.56 COMPLETE UPPER RECEIVER ASSY

050806000001 430106122
Designed in conjunction with PWS & FM Products, the Brownells BRN-180S® Complete Upper Receiver is the newest iteration of the BRN-180® Upper Receiver, which was inspired by the Armalite® AR-180 of the 1960s. The BRN-180S® shares a large chunk of components with the BRN-180® but introduces key features to improve reliability and usability in a short configuration. With an entirely self-contained recoil system, the BRN-180® can be mounted to lower receivers without a buffer tube. This allows for easy compatibility with folding stocks and rear picatinny adapters. Recoil guide rods and buffer easily remove from the rear when removing the upper receiver from the lower. Bolt and carrier easily slide out when removing the charging handle at the rear. Large ejection port allows for ease of access for cleaning. Lightweight barrel profile sits inside the slim handguard, making for an extremely lightweight package, even with the piston driven system. Top picatinny rail sits extremely low compared to other piston systems, allowing for broad compatibility with common AR-15 height optic mounts and sights. Barrels feature a 223 Wylde chamber to function with the broadest spectrum of 223 Remington and 5.56x45mm NATO ammunition. Barrels do not come with a muzzle device. This allows for ease of installation of your preferred muzzle device, which is handy to reach an OAL of 16 inches for pined and welded devices of your preference. Free float MLOK handguard is free floated, and can easily be removed with one large screw located on the bottom of the receiver. This screw engages the rear of the barrel, pulling the handguard tight up against the receiver. Easily removed handguard allows for quick access to the BRN-180® gas system. Gas plug has two settings: U = Unsuppressed S = Suppressed Ultra-reliable AR-180 piston operating system Compatible with current mil-spec AR-15 lowers Machined 7075 T6 aluminum receiver & handguard - hardcoat anodized finish 13.9” or 14.5” Nitride Finished Barrels .223 Wylde chamber Button rifled bore 1-8" twist for both the 223 Wylde ½"-28 threaded muzzle for 223 Wylde Molded polymer ejection port cover All NFA rules apply Muzzle device is installed with a lock washer. To remove, secure lock washer with wrench while unscrewing the muzzle device. User removal of the trunnion, barrel and trunnion screws is not recommended. Removal of the trunnion screws will void our Lifetime Guarantee.
