Enhanced Performance Round. It was first made public in 2014 and completed development in mid-2016 as the Enhanced Performance Magazine. The magazine uses a blue follower and a tan body which presents the rounds with a better angle to the weapon's feedway, preventing the hardened steel tip of the EPR from contacting the aluminum feed ramp of the M4 carbine, increasing mean rounds between stoppage by 300%.
