810108160380 CORE ELITE OPERATIONS CE0-15 BATTLE SERIES 300 AAC BLACKOUT COMPLETE PISTOL UPPER RECEIVER FOR AR-15 The Core Elite Operations CEO-15 Battle Series Complete .300 Blackout Pistol Upper is engineered for compact performance, reliability, and hard use. Designed as a ready-to-install upper assembly, this configuration is optimized for short-barrel platforms and suppressed-capable applications. The upper receiver is forged from 7075-T6 aircraft-grade aluminum and finished in a durable black anodize. The system is built around a 10.5” barrel constructed from 4150 Chrome Moly Vanadium steel. The barrel is equipped with a custom-designed muzzle brake machined from hardened 4150 steel and finished in black nitride. This pistol upper utilizes a pistol-length gas system with a low-profile .750” gas block and a 304 stainless steel gas tube, providing reliable cycling and consistent performance in a compact configuration. Surrounding the barrel is a custom-designed 10” lightweight yet rigid M-LOK free-float handguard. Large ventilation windows along the top rail promote increased airflow, aiding in heat dissipation during extended use. Internally, the upper receiver is outfitted with a Mil-Spec bolt carrier group manufactured from heat-treated 8620 steel. The BCG includes a No. 158 steel bolt, a shrouded firing pin, and a chrome-lined interior. The gas key is secured using Grade 8 fasteners and properly staked to Mil-Spec standards to ensure smooth cycling and long-term reliability. Completing the assembly is the ambidextrous CEO CARNO charging handle, delivering smooth and consistent manipulation of the bolt during both loading and unloading. All Core Elite Operations complete upper receivers are backed by a lifetime warranty covering all manufacturing defects. SPECS Manufacturer: Core Elite Operations, Inc.
