Core Elite Operations CEO-15 Battle Series Complete Pistol Upper

Our Complete Uppers are built on our 7075 T6 aircraft-grade aluminum receiver with a 10.5″ 4150 Chrome Moly Vanadium  Steel barrel which is coated in a corrosion resistant QPQ black nitride finish. All our barrels are finished off with our custom designed muzzle brake cut from 4150 hardened steel and coated in a black nitride finish. Our barrels feature a pistol length gas system with a .750 diameter low pro gas block and 304 stainless steel gas tube. Every complete upper comes equipped with out custom designed light weight yet sturdy 10″ handguard. These MLOK style handguards feature large windows along the top rail allowing better airflow through the rail to keep your barrel cooler. Internally, our upper receivers are equipped with our Mil-Spec 8620 heat treated steel bolt carrier group or BCG. The BCG contains a N0. 158 steel bolt with a shrouded firing pin and Mil-Spec chrome lined interior. The gas key on the BCG is secured with grade 8 fasteners and staked to Mil-Spec standards guaranteeing reliability and smooth cycling. The final piece of our complete uppers is our ambidextrous CARNO charging handle providing smooth operation of the bolt when both loading and unloading the weapon.

All Core Elite Operations Upper Receivers are covered by our hassle free Lifetime Warranty on all manufacturer defects.
