PA10 18" Mid-length AR-10 Barrel .308 Win 1:10, Nitride - 7779364

Overview

The PSA PA10 18" mid-length AR-10 barrel is chambered in .308 Winchester and constructed from 4150V chrome-moly steel. It features an A2 profile, a gas nitride finish, and a 1:10 twist rate. The barrel is threaded 5/8x24 at the muzzle, uses a .750-inch diameter gas block, and features an M4 barrel extension. This barrel is designed specifically for the PSA PA10 platform. Because AR-10 designs vary significantly between manufacturers, Palmetto State Armory recommends using their parts exclusively with their own upper and lower receivers to ensure proper fit and function, rather than mixing parts from other manufacturers.
