Description
 
The Brownells BRN-180S Gen2 upper receiver in caliber 300 Blackout features a self-contained recoil system, and can be mounted to milspec AR15 receivers without needing a buffer tube to function. This allows for easy compatibility with folding stocks and rear picatinny adapters. A lightweight barrel profile sits inside the slim handguard, making for an extremely lightweight package. The free-float MLOK handguard can be removed with one screw that also engages the rear of the barrel, pulling the handguard tight up against the receiver.

User removal of the trunnion, barrel and trunnion screws is not recommended. Removal of the trunnion screws will void the lifetime guarantee. All BRN-180 upper receivers are test fired at the factory, and may display signs of firing.
