The PTS®Enhanced Polymer Magazine, or EPM for short, is a new type of Mid-capacity Polymer Magazine for AEGs. The EPM is a truly unique AEG magazine, inside and out.

Externally it features a Dupont Zytel Polymer shell, with recessed panels for better grip, and unique magazine well guides that reduce snagging when the magazine is drawn from and reinserted into pouches. The bullet window with the fake 556 rounds isn’t just for show. When the magazine is fully loaded, at the base of the see-through bullet window, an orange follower comes into view. This is a remarkable design feature unique to the EPM as 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. It also acts as a visual indicator for the user to know when to stop loading the magazine.

Another notable feature of the magazine is the base plate. The bottom of the base plate has been designed with an angled surface and a rubber over-mold 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. The angled surface is minimized to the point that it is functional, yet still comfortable in the hand when drawn from pouches and also does not inhibit the closure of flaps on closed top magazine pouches.

The base plate has also been designed with a ribbed ledge which promotes easier extraction of the magazine from deep magazine pouches and can help the end user with correctly indexing the magazine.

This mid-capacity AEG magazine holds 150rounds with the same reliability that all PTS magazines have long been famous for. It is compatible with Version 2 based M4 AEGs by TM, KWA, PTS PDR-C, PTS ERG series, PTS Masada, G&P, the VFC 416, the CA 416, and the AMOEBA AMVariants.
