Brownells AR-15 M16A1 Retro Barrel Assemblies are offered in multiple lengths inspired by the classic A1 profile. These barrels are machined from hardened 4150 chrome-moly steel and MPI inspected, finished in black phosphate or nitride bore variants, and chambered for 5.56 NATO. Selected lengths feature 1-7 or 1-12 twist rates and include a carbine-length gas system on shorter configurations and rifle-length gas on the longer 20 inch version. Muzzle threads are 1/2-28, with a front sight base installed on applicable variants. Retro styling suitable for XM177 reproductions and lightweight AR builds.
