The PTS Enhanced Polymer Magazine is their new 150 Round Mid-capacity Polymer Magazine for AEGs. Externally it features a Dupont Polymer shell, with recessed panels for better grip, and unique magazine well guides that reduce snagging.
When the magazine is fully loaded, at the base of the see-through bullet window, an orange follower comes into view as well as the fake 556 bullets which only for show. It allows the end user to pick up any EPM magazine and immediately know if the magazine is filled to capacity and ready to go as it also acts a visual indicator for the user to show that it's full.
The bottom of the base plate has been designed with an angled surface and a rubber overmold on the lower face. This combination of features allows the end user to rest the gun on any flat shooting platform and have more surface contact with better traction and therefore greater stability.
