BROWNELLS BRN-180S™ GEN2 7.62X39 10.5IN COMPLETE UPPER RECEIVER ASSEMBLY

BRN-180™, now in 7.62x39.

WIth the same layout and configuraiton of the 223 models, the 7.62x39 BRN-180™ packs a big punch in a small package. Feeding from AR-15 7.62x39 magazine, the AR-180 inspired design provides reliable perforance with a modern feature set.

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!)
