COLT LE6920 CONVERTED TO M4A1 BLOCK II 14.5" CARBINE

This clone began as a LE6920 in 2017. After 8 years of sourcing the right parts and multiple iterations, this is the result. The primary modifications include replacing the 16" C MP barrel with a 14.5" C MP barrel featuring a MK12 style gas block and pinning/welding a Surefire 4-Prong. Next, acquiring a Daniel Defense RIS II rail in FDE is essential. This will serve as the foundation for completing the clone. Finally, obtaining the correct optics from the BLOCK II program will be the last step. The parts list below details the optics, sights, and other small items you'll need.

*We do have the correct 14.5" C MP barrels in stock if you cannot find them*
