BRN-180 GEN 2 COMPLETE UPPER RECEIVER WITH MI SIDE FOLDING STOCK
BRN-180® Upper Receiver Group Gen2 – Reliable Piston System Made Even More Versatile
Designed in conjunction with PWS & FM Products, the Brownells 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!)
