PTS EPM Mid-Cap Magazine for M4 / AR15, 150 BBs - Tan

Mid-Cap EPM Magazine for M4 / AR15 by PTS

The PTS Enhanced Polymer Magazine (EPM) is one of the best Mid-Cap magazines for AEG M4 / AR15 rifles, designed in the style of MAGPUL M2/M3 30-round magazines. It retains an optimal 150 BBs capacity and features the legendary feeding reliability of all PTS magazines. The body is made of highly durable DuPont Zytel polymer, making it tough enough to withstand battlefield conditions. A special feature includes an orange full-load indicator that appears in the window when the magazine is fully loaded, allowing for quick status checks. Similarly, when the last BB is fired, the orange follower is visible, signaling an empty magazine.
The improved baseplate design features an angled support that improves stability when shooting from a rest and allows for easier handling when retrieving the magazine from pouches. The textured surface on the front and back enhances grip and compatibility with Magpul Mag Couplers.
