Brownells announced the release of their shorter 10.5 inch BRN-180 upper receiver. These BRN-180 uppers are completely compatible with The AR-15 pattern lower receivers. Brownells teamed with Primary Weapon Systems and FM Products to create the BRN-180 and the BRN-180S.

Brownells states “The BRN-180S is obviously shorter than the standard BRN-180, with a 10.5 inch barrel. The free float M-LOK handguard mated to the assembly is also shorter, terminating just in front the gas block. The gas block is where the large differences are between the prior BRN-180 and the BRN-180S. The BRN-180S gas piston is adjustable from the front the gas block, making the switch to suppressor use quick and easy. The gas block vents excess gas to the front when suppressed, to ensure smooth cycling.”
