Product Details
This upper parts kit gives you everything you need to build or upgrade an AR15 - barrel, bolt carrier group, gas tube, and gas block all in one package. The 14.5" barrel is threaded for a muzzle device and uses mid-length gas system tuning, which tends to run a little smoother than shorter setups. It's chambered in 223 Wylde, so it'll shoot both 223 and 5.56 ammo reliably. Rosco makes solid, no-nonsense barrels, and this sand blasted silver finish looks good and handles hard use just fine.
