The Core Elite Operations CEO-15 Battle Series Pistol is a purpose-built firearm designed for hard use and will withstand the abuse of time. It is built on forged CEO-15 7075 T6 aircraft-grade aluminum receivers sets and a custom designed CEO-15 10” M-LOK lightweight handguards. Mounted inside the handguard, each rifle is equipped with a 10.5” 4150 Chrome Moly Vanadium Steel barrel which is protected with a QPQ corrosion resistant black nitride finish. The barrel is finished with a custom designed muzzle brake that sits seamlessly inside the business end of the handguards. Each barrel is matched to a black nitride Mil-Spec No. 158 steel bolt and 8620 steel heat treated bolt carrier group (BCG). Each BCG comes with a shrouded firing pin and Mil-Spec chrome lined interior. The gas key is secured to the carrier with Grade 8 fasteners and properly staked to Mil-Spec guaranteeing reliability and smooth cycling. To charge the weapon system, we include the CEO CARNO ambidextrous charging handle to ensure smooth and clean manipulation when loading and unloading the weapon system.
