This kit allows users to upgrade their existing lower receivers with a factory-built solution that prioritizes reliability under harsh operational conditions.

At the heart of the Colt Epr Upper Kit 5.56 11.5" Blk is a high-grade chrome-lined barrel chambered in 5.56x45mm NATO to ensure longevity and consistent accuracy during high-volume fire.

This free-floating rail design prevents torque on the barrel, ensuring that your point of aim remains consistent regardless of how you brace the firearm. Precise manufacturing tolerances and a standard carbine-length gas system work in tandem to provide a smooth recoil impulse and cycling reliability.
