Keeping in line with the rest of Brownells BRN-180 project, the BRN-180 Folding Stock takes its origin and styling ques from the original AR-180 but incorporates more modern materials and functional design to offer a stock that looks the part and performs great. The stock itself is a polymer construction while the folding mechanism has been designed from the ground up and is a metal construction. The 1913 Picatinny mounting system has been improved for better fitment on BRN-180 style lower receivers, and the lock-up in the fixed position has been improved as well for a tighter lock-up than ever. The stock folds to the shooters left and is a slim design so it adds minimal width Mfg: Brownells
