10.5″ 5.56 NATO Complete Pistol Upper with 12″ KeyMod Rail
This 10.5″ 5.56 NATO complete AR pistol upper runs a chrome moly barrel with a phosphate finish and 1:7 twist on a carbine-length gas system, wrapped in a 12″ KeyMod handguard. It’s threaded 1/2″x28 off a .750″ gas block and ships with the gas block and gas tube installed on a black mil-spec upper receiver with dust cover and forward assist — just add a BCG and charging handle to finish the build. Check out the 7.62×39 version if you’d rather build in a different caliber, or browse more AR pistol upper build kits.
