    Good news for AR-18/180 lovers looking for that shorter package, Brownells have introduced the new BRN-180S, a short barreled version of their BRN-180 upper assembly. Now available for pre-order the BRN-180S has a 10.5″ barrel with an M-LOK handguard and the new short barrel has a .223 Wylde chamber.

    Here’s what Brownells had to say about their short barrel BRN180

    Hot on the heels of one its most-exciting SHOT Show launches ever, Brownells has unveiled the BRN-180S – the new, short-barreled version of the BRN-180 complete upper assembly debuted at the 2019 SHOT Show.

    Designed in conjunction with Primary Weapons Systems and FM Products, the BRN-180S retains all the desirable features of its big brother, but has a  10.5″ barrel for those wishing to build an AR-180-style pistol, or –with the required ATF paperwork and tax stamp – a short-barreled rifle (SBR).

    Another new feature on the BRN-180S is a clearly-marked adjustable gas system, allowing the user to quickly tune the upper for either unsuppressed or suppressed shooting.

    “The reaction to our 2019 SHOT Show announcement of the original BRN-180 was one of the largest, most-positive we’ve seen,” said Brownells Director of Product Management Paul Levy. “The most-common request from customers was for us to come out with a short-barreled version of the BRN-180. Thanks to PWS and FM Products, we were able to do that.”

    Available for pre-orders now, the BRN-180S will make its first public appearance at the 2019 NRA Annual Meetings and Exhibits April 26-28, in Indianapolis, Indiana.

    Built around a short-stroke piston system, the BRN-180S drops onto any mil-spec AR-15 lower and makes it easy to attach either a folding pistol brace or folding stock.

    Just like the BRN-180, the BRN-180S can be fired while folded.

    • 10.5″ barrel
    • .223 Wylde chamber
    • 1-8″ twist rifling

    • Easy-to-remove M-LOK® handguard
