The Colt LE6933 EPRII Upper 556 11.5 HUX is a complete upper receiver built on Colt’s proven carbine platform, combining TDP-spec components with certified mil-spec materials for dependable performance. This upper features an 11.5" Colt-spec CrMoV steel barrel with a carbine-length direct impingement gas system, surrounded by a slim M-LOK compatible rail for mounting lights, grips, and other accessories. A HUXWRX QD 556 flash hider is installed at the muzzle, and the assembly includes a mil-spec chrome-lined bolt carrier group for long-term durability.

This upper is designed to mate with standard AR-15 lower receivers, offering a compact configuration well suited to training, range use, and general-purpose patrol-style setups where reliability and control are priorities. The anodized black finish and low-profile rail keep the package streamlined for accessory mounting without unnecessary bulk. Backed by Colt’s long history of building professional-grade carbines, the LE6933 EPRII Upper delivers a refined, duty-ready top end for shooters who value consistent performance.
