PTS EPM-LR Mid-Cap Magazine for SR-25 150 BBs — Black

The PTS EPM-LR is a 150-round mid-cap polymer magazine for SR-25 AEG replicas, designed around the profile of the MAGPUL AR-10 magazine. It is aimed at players running the SR-25 platform in airsoft who need reliable feeding with heavier BBs or at the higher rates of fire typical of DMR builds.

The body is made from DuPont Zytel polymer, a material with high resistance to impact and deformation that holds insertion tolerances even after extended use. The EPM texture improves grip during fast reloads, while the updated base pad has an angled profile that increases stability when the rifle is rested on a bench or bipod and makes it easier to draw from a magazine pouch without adjusting your grip. As a 150-round mid-cap, it produces no BB-rattle — a tactical advantage over hi-caps — but requires manual loading with an external speed loader, which is not included.

The high-efficiency internal spring and PTS-designed follower provide consistent feeding with BBs up to 0.49 g without jams, a relevant figure for anyone setting up a low-rate DMR replica with heavy BBs. The orange follower becomes visible when the magazine runs dry, giving a clear visual indication without manual inspection. The low-friction inner shell reduces drag even at higher rates of fire. Field-stripping for maintenance requires no tools.
