D-Day DMAG Adjustable 30/130rnd Magazine for M4/AR-15 AEGs

  • Polymer construction
  • 30/130rnd Variable capacity mag
  • For M4/AR15 Airsoft AEG rifle

Looking for a real cap magazine for Milsim that can double as a mid-cap for regular Airsoft skirmishes? The DMAG from D-Day is a high-density polymer magazine, styled after the latest "416" style magazine, complete with reinforcement ribs on either side and a redesigned shell shape to prevent the magazine from being over-inserted during a fast reload and damaging your HOP-up unit. This magazine is constructed with a high-density polymer shell and polymer internals with a steel feed spring and can be loaded through the fill/feed port at the top of the magazine.

Full description


The DMAG from D-Day is constructed from high-density polymer and can be converted between 130 round capacity, perfect for walk-on skirmishes and 30 round capacity for those Milsim scenarios where ammo capacity is restricted for realism's sake.

To adjust the capacity of the magazine, the internals need to be removed from the shell. In order to do this, you will need to press the button in the centre of the base plate and slide the base plate off to the rear of the magazine.  With this step complete, you should be able to remove the magazine internals from the shell by pushing them downwards from the top. With the internals removed, you will find a button on the right side of the internal shell. This button controls the capacity of the magazine, and can be pushed down and slid forwards to select the 30 round restricted mode. With your capacity selected, the magazine internals can be pushed back into the external shell through the bottom, and the base plate can be reinstalled.

This magazine is compatible with M4/AR15 AEG rifles based on the original Tokyo Marui design, and will also work in 416 and SCAR-L style AEGs.
