H&R A2 Carbine 5.56 NATO Rifle, 14.7" Barrel Pinned and Welded to 16", Black The Harrington & Richardson A2 Carbine is a complete black 5.56 NATO rifle built around an A2-style fixed stock and a pencil-profile barrel. The 14.7-inch barrel is supplied with the muzzle device pinned and welded to bring the barrel assembly to 16 inches. That distinction is part of the factory configuration and is separate from the firearm's overall length. An M16A2 upper with M4 feed ramps pairs with the H&R M16A2 COTS Special Forces lower receiver. The forged 7075-T6 receiver construction, A2-style grip, and carbine handguards create a consistent retro carbine layout. Six-hole handguards with heat shields and the specified standard mil-spec trigger group complete the principal furniture and control details. Barrel and Gas System The chrome-lined 4150 chrome moly vanadium barrel has a parkerized exterior, a 1:7 twist rate, and a carbine-length gas system. The A2-style muzzle device completes the factory barrel assembly, while the fixed stock and A2-style grip define the carbine's furniture configuration.
