PTS® EPM M4 GBBR Magazine (DE)

A rather heavy but reliable 38 Round Magazine with the EPM design taken into account. This particular magazine is much more reliable than the previous version, it may hold 2 less BBs but holds a lot more gas within its resevior. It has enough gas to go through the entire clip and a little more so you don’t ever have to worry about running out of gas before you run out of BBs!
