The Colt M4 LE6933 EPR Upper Group 11.5in Stripped is a compact AR-15 upper built around Colt’s Enhanced Patrol Rifle concept, pairing a chrome-lined 11.5 inch barrel with a Centurion Arms free float M-LOK handguard. This stripped upper arrives without a bolt carrier group or charging handle, giving builders the flexibility to choose their preferred components while still benefiting from Colt’s proven barrel and receiver geometry.

With its short carbine-length barrel chambered in 5.56x45 NATO and 1-7 twist rate, this upper is well suited for range use, training, and building a compact AR-15 configuration where maneuverability matters. The free float M-LOK handguard offers generous mounting space for lights, grips, and sling hardware, while the matte black finish keeps reflections to a minimum. It’s a practical foundation for enthusiasts who appreciate Colt’s long-standing reputation for reliable AR platforms and careful attention to barrel quality.
