Enhanced Polymer Short Magazine EPM 1-S (170rd - FDE)

The PTS EPM1-S magazine for AEG, manufactured using the same technology as our EPM1, is a short 20-round length M4-type magazine offering an incredible 170 BB capacity and the same reliability for which all PTS magazines are known. It is compatible with most AR-15 M4 AEG airsoft replicas, including models from Tokyo Marui, KWA, G&P, VFC (including the HK416), PTS PDR-C, the PTS ERG series, PTS Masada AEG, AMOEBA AM variants, and many more. It is available in Black and Dark Earth (FDE).

About the EPM1

The PTS Enhanced Polymer Magazine ONE, or EPM1, is the most advanced and highest-capacity spring-powered AEG magazine ever produced. Aptly named EPM1, this magazine marks several "firsts":

• First collaborative development between PTS and Odin Innovations.

• First spring-powered AEG magazine to rival the capacity of a high-cap magazine.

• First AEG magazine with a "fuel gauge" style window to indicate total or remaining BB load.

• First magazine to achieve high loading capacity and reliable performance at high rates of fire.

External Design

The EPM1 has been significantly redesigned. Like the original EPM and all PTS polymer products, its shell is made from Dupont Zytel® polymer, making it extremely strong and durable. It also retains the continuous magazine well guides, reducing snagging when inserting or removing it from pouches or the airsoft replica. Additionally, it features the distinctive EP texture on the shell to enhance grip and tactile feel.

The magazine spines have been redesigned with ribbing for improved grip and allow compatibility with the Magpul Maglink® coupler.

Base Plate

The EPM1 base plate has also been completely redesigned. Its new sliding insert system makes it more durable and impact-resistant in case the magazine is dropped. It is also significantly slimmer than the first-generation EPM, making storage and transport easier.

The base is angled to function as a monopod during supported shooting. As in previous versions, it includes a dot matrix for magazine identification marking. The ribbed front edge is now integrated directly into the magazine body, making extraction from magazine pouches or tactical vests easier.

Enhanced Follower

The new enhanced follower is the result of collaboration with Deranged Designs. This design focuses spring pressure directly onto the BB stack, preventing lateral pressure or pressure against the internal channel walls. This significantly improves BB feeding speed and consistency, while also preventing jams caused by BB misalignment.

Load Indicator (“Fuel Gauge”)

The most innovative and visible feature of the EPM1 is its load indicator window. Thanks to the exclusive orange indicator, you can immediately tell whether the magazine is full, partially loaded, or empty.
When fully loaded, the indicator appears at the top of the window. As you shoot, the indicator descends until it reaches the bottom, indicating the magazine is empty.
