PTS X Speed EPM magazine has a 150 round bb capacity with the same reliability that all PTS magazines have long been famous for. It is compatible with Version 2 based M4 AEGs and M4 HPA Systems.
The magazine features a Dupont® Polymer shell, with recessed panels for better grip, and unique mag well guides that reduce snagging when drawn in/out of pouches. The mock ammunition window serves as an ammo indicator. When the magazine is fully loaded, a bright orange follower comes into view. An angled, rubber overmold baseplate makes for easy indexing and fast reloads.
