The benchmark short M4 mid-cap airsoft magazine receives a precision performance upgrade with the PTS EPM1-S RX. Maintaining the compact 20R profile preferred by players seeking a low-profile setups and prone stability, the EPM1-S RX delivers an impressive 170-round BB capacity without the rattle of high-cap magazines.
The primary upgrade in the EPM1-S RX lies in its completely re-engineered internal shell tooling. Identified by its distinct grey polymer colour and surface EPM1-S RX markings, the new internal housing features refined dimensional tolerances and a smoother internal BB channel. This design optimisation ensures reliable, consistent feeding across high rate-of-fire AEG setups, housed within the battle-tested DuPont™ Zytel® high-strength outer shell.
Features a brand-new grey internal shell with revised tooling dimensions, resulting in a smoother BB channel for unimpeded feeding performance.
Delivers a dense 170-round capacity within a short-form factor magazine, eliminating spring noise while providing ample ammunition for extended engagements.
Includes an orange mag level indicator that moves downwards as BBs are expended. Rests at the top when fully loaded and reaches the bottom when empty for immediate visual capacity checks.
Constructed from ultra-durable DuPont™ Zytel® reinforced polymer to endure hard field use, drops, and rough tactical environments.
Co-designed with Deranged Designs to maximise feeding speed and prevent BBs from slipping past the follower, effectively eliminating jams.
The angled flat basepad allows shooters to rest the rifle on flat surfaces for enhanced shooting stability. Includes a front lip for easy pouch indexing and a dot matrix pattern for custom identification marking.
Seamless outer contours reduce snagging when drawing from pouches or inserting into rifle magazine wells.
