Description
PTS/KWA EPM ERG (30 or 120 Rounds – Black)
The PTS EPM ERG is a variable-capacity Enhanced Polymer Magazine made for ERG (Electric Recoil Gearbox) rifles from PTS and KWA. A switch on the base lets you choose between a realistic 30-round mode and a higher 120-round mode, so one magazine can suit both milsim and regular skirmish games.
PTS Syndicate is known for its officially licensed accessories, and the EPM is modelled on the familiar polymer rifle magazine shape, giving the right look and feel in pouches and on the rifle.
Build and handling
The EPM shell is made from DuPont Zytel reinforced polymer, according to retailer listings. Recessed side panels give a good grip with gloves on, and magazine well guides help reduce snagging when drawing it from a pouch or seating it in the rifle.
The front of the base plate has a dot matrix area where you can mark a number or symbol, which is helpful for keeping track of your magazines or identifying them at a busy safe zone.
Two capacity modes
Flick the switch on the base to change between the 30-round and 120-round modes. The lower setting is popular at milsim events and sites with a magazine-capacity limit, while 120 rounds reduces how often you need to reload in faster games.
As with any magazine, load it with a speedloader and good-quality seamless BBs for reliable feeding.

Care and maintenance

Use clean, seamless BBs, as damaged or dirty BBs can cause feeding problems.
