The Colt EPR-II (brand part no. LE6933-EPRII) is a 5.56x45mm short-barrel rifle built on an M4 cage-code-marked upper receiver forging paired with a Colt lower, giving it the same receiver pedigree as Colt’s military and law enforcement carbines. An 11.5-inch threaded barrel keeps the package compact, and the M-LOK handguard offers a continuous top rail with seven orientations of M-LOK slots plus two steel-reinforced QD sling points. Magpul MBUS 3 folding sights, a Magpul enhanced trigger guard, an ambidextrous safety selector, and a Magpul SL stock round out a rifle built for shooters who have completed the transfer process for a short-barrel configuration.
