Long-proven, ultra-dependable short-stroke gas piston operating system based on the AR-180.
This complete upper receiver is part of the Brownells® extensive BRN-180® line of AR-15 compatible gas piston uppers, which was inspired by the highly advanced Armalite® AR-18 / AR-180 rifles of the 1960s. The BRN-180's adjustable gas block can be switched between two settings, simply by flipping a small lever: "S" is for use with a sound suppressor, "U" for normal, unsuppressed fire. The lever is easy to access through a convenient cutout in the handguard. With an entirely self-contained recoil system, the BRN-180S® can be mounted to a standard "mil-spec" AR-15 lower receiver without a buffer tube. This enables easy compatibility with folding stocks and adapters for stocks that mount to M1913 Picatinny rails.
