The new Brownells BRN-180 and BRN-180S Gen2 upper receivers were designed in conjunction with PWS and FM Products to incorporate many improvements over the AR-15 that Eugene Stoner created in the AR-18/AR-180 rifles originally introduced in the 1960s. Key features that make the BRN-180 the \"revolutionary evolution\" of the AR-15 platform include:
Ultra-reliable, short stroke gas piston operating system NO buffer tube! Ideal for a folding stock Can be fired with a folding stock FOLDED! Adjustable gas block lets you control gas flow for a sound suppressor Rock-solid Picatinny/M-LOK handguard easily detaches by removing ONE screw Muzzle threads: 1/2\"-28 tpi The BRN-180 barrels are button rifled with a 1-8\" twist rate
