Tokyo Marui AA12/SGR12 Angel Custom Drum Mag Adaptor

thingiverse

This is an adapter for the Tokyo Marui AA12 and the Angel Custom drum mag. The mag is smaller than the original TM mag, feeds just as well or even better, and requires slightly less winding to load. It holds around 1700 rounds, though I haven't taken exact measurements yet. This adapter also fits the SGR12 model. In the near future, I plan to release an AA12 edition of this adapter. This new version will be thicker and match the shape of the AA12 mag-well perfectly, with a fatter fill tube that increases its capacity slightly. I also hope to create a list of parts for a sound-activated switch in the future. This would greatly relieve users of one of the least enjoyable aspects of owning an AA12, which is pushing the winding button constantly. The switch won't be complicated to make and can be assembled from basic components available on AliExpress with simple soldering. This adapter has already been printed and tested during gameplay. It fits snugly into place and, when printed vertically, its mounting system rail provides excellent strength. To modify the Angel Custom mag for use with this adapter, simply remove the original feed spring and replace it with a longer one. This is a straightforward process that can be completed in no time. The replacement spring can be purchased at RetroArms.com under the "Other" category, specifically the Bowden Spring for M249/M60 mags.
