Full description


The Shell of the magazine is constructed from high performance reinforced Polymer and is based on the Enhanced Polymer Magazine (EPM) design. The magazine holds up to 40 rounds, and features Polymer feed lips, and is filled from the top using an Airsoft speedloader. The magazine is gassed from the bottom into a recessed fill valve to prevent dirt build-up and is filled with any Airsoft green gas. The magazine features textured side panels for easy grip, and a smooth shell which makes the magazine easier to draw by preventing snaggage. The bottom of the magazine features a removable base plate which features a Dot Matrix panel which can be coloured, creating identification marks to allow the user to keep track of used magazines. This magazine is a must buy for any Airsoft skirmisher who owns an LM4 or compatible GBBR platform, providing better efficiency over standard STANAG style magazine.

Special Instructions:

We recommend that your gas magazines always have some gas left in them even when not in use, in doing this you are preserving your seals and ultimately making your magazine last longer. We recommend that you first fully empty your magazine, then add a small squirt of maintenance gas, which helps keep the O-Rings lubricated.
