NOTE: This upper assembly has a barrel less than 16” in length. These uppers are intended for use in AR pistol or legal short-barreled rifle builds. Other configurations may violate Federal law.

This Ghost Firearms 5.56 Barreled AR-15 Upper Receiver is made from high quality parts at an affordable cost. This upper features a 7.5” M4 profile barrel that is made from 4150 chrome moly steel barrel with a Nitride finish. The 1:7 twist rate is optimal for heavier grain 5.56 ammo and the pistol length gas system helps to cycle with such a short barrel. The end of the barrel features a flash can which fits underneath the 9” M-LOK compatible free float handguard. The handguard matches up to the M4 flat top upper receiver which is made from 7075-T6 aluminum and hardcoat anodized black. The upper receiver is finished forward assist and dust cover but does not include BCG or charging handle. Compatible with any Mil-Spec lower receiver, you can build an affordable AR pistol in no time.
