Colt LE6920EPRII 5.56mm 16.1" Bbl Sights Matte Black Upper Receiver Conversion Kit LE6920-EPRII-CK

The Colt LE6920 EPRII Upper Receiver Conversion Kit is a complete centerfire upper assembly chambered in 5.56mm NATO, updating Colt's iconic law enforcement M4 line with contemporary, duty-ready modular enhancements. This factory-assembled kit provides a drop-in option to convert any standard AR-15 lower receiver group into an Enhanced Patrol Rifle (EPR) Gen II platform. It features a 16.1-inch chrome-lined carbon steel barrel with a 1:7" right-hand twist rate and a direct gas impingement system housed within an updated free-floating aluminum M-LOK handguard that completely isolates the barrel from hand pressure to maximize shot-to-shot accuracy.
