The PTS Enhanced Polymer Magazine (EPM) is a new take on the mid-capacity polymer mags for airsoft AEG’s. Constructed from Dupont Zytel Polymer, this magazine is remarkably rugged and features a solid weight. The recessed panels allow for a better grip and the unique mag well guides help reduce the possibility of snagging when being drawn or reinserted into pouches. The bullet window features realistic looking dummy 5.56 rounds and even has a visual indicator at the bottom of the clear window to show the magazine is full (orange follower will be visible when fully loaded).The base of the magazine features a rubber foot to allow the operator to use the magazine itself as a makeshift mono pod for improved stability when trying to make an accurate shot.

Compatibility: For Tokyo Marui, Matrix, APS, G&P and other compatible M4 / M16 Series Airsoft AEG Rifles
Capacity: 150rds (No Winding Required)

    Gun was a bit picky with what mags it would accept but these PTS EPMs are the real deal and don’t skip a beat. Look good, feel good, solid construction, never jam. What more could you ask for from a mag. 10/10
