Best AR-15 Upper 2019: Brownells BRN-180 & BRN-180S

U.S.A. –-(Ammoland.com)-  Brownells has done gun owner’s a service with the Retro line of guns and has taken that a step further with the BRN-180 upper receiver. The BRN-180 (16″ & 18″ uppers) and the BRN-180S (10.5″ version) are both the first installments to the Retro line of firearms that are upgrades for an AR-upper that is fully compatible with any standard mil-spec AR-15 lower receiver. Unlike any other AR-upper, the BRN-180 relies on a different operating system with a design that reaches back to the original improvements made to the M16 platform.

Brownells BRN-180 Upper Receiver

Designed in conjunction with PWS & FM Products, the Brownell’s BRN-180 Complete Upper Receiver is inspired by the Armalite AR-180 of the 1960s. Developed as a successor to the original AR-15, the AR-180 was a civilianized version of the AR-18, itself an upgrade on the M16 platform. The BRN-180 incorporates many of the AR-18/AR-180 improvements – including its robust and reliable gas piston operating system. (Yes, the originators of the AR-15 / M16 eventually embraced a piston!)

Like the original, the BRN-180 bolt carrier rides smoothly on a PAIR of guide rods. The carrier is buffered at the rear by a built-in polymer buffer with a molded-in steel plate that captures the guide rods. The bolt replicates the original AR-180 bolt design, right down to its use of a standard AR-15 extractor.

Yes, the BRN-180 upper receiver is fully compatible with any standard, mil-spec AR-15 lower receiver.
