The Colt M4 LE6933 EPR Upper Group 11.5" Stripped is a no-frills, parts-ready upper receiver built for shooters who already have a lower and want to finish the build their way. This stripped configuration gives you the receiver, barrel, and handguard without the bolt carrier group or charging handle, so you can source those components to match your setup exactly. It's a smart option for builders who've got a preferred BCG or handle in mind, or who want to keep costs down by reusing existing parts.
The LE6933 starts with a chrome-lined, button-rifled barrel in 11.5 inches—a compact length that balances firepower with maneuverability in an AR platform. The 1-7 twist rate cycles standard 5.56 ammunition reliably and handles heavier projectiles without hesitation. A phosphate finish protects the steel against corrosion and wear during hard use. The upper sits atop a Centurion Arms free-float M-LOK handguard, which isolates the barrel from the furniture for consistent accuracy and gives you genuine modularity—attach lights, vertical grips, or other gear where you need it.
Whether you're building a home-defense carbine, a short-barreled precision rifle, or a do-it-yourself tactical setup, the LE6933 upper strips away the excess and lets you control every detail of the final gun. Drop it on a compatible AR-15 lower receiver, add your chosen BCG and charging handle, and you've got a rifle tuned to your preferences.

The 1-7 twist rate is optimized for 5.56 NATO and handles a full range of projectile weights reliably, including heavier rounds.
Yes. The Centurion Arms free-float M-LOK handguard is designed to accept M-LOK-compatible accessories like lights, grips, and rail sections wherever you need them.
