Brownells BRN-180S Gen 2 Complete Upper Receiver 223 Wylde 14.5" Black

Designed in conjunction with PWS & FM Products, the Brownells BRN-180SA(R) Complete Upper Receiver is the newest iteration of the BRN-180A(R) Upper Receiver, which was inspired by the ArmaliteA(R) AR-180 of the 1960s. The BRN-180SA(R) shares a large chunk of components with the BRN-180A(R) but introduces key features to improve reliability and usability in a short configuration. With an entirely self-contained recoil system, the BRN-180A(R) 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 t Mfg: Brownells
