Airsoft P90 M4 Mag Adapter (Bren 90)

thingiverse

This is my adapter to convert an airsoft P90 to use standard M4 magazines. This is still currently a work in progress. You will require 3 M3 countersunk screws (designed to take standard airsoft gearbox countersink screws). Two of these are for attaching the front to the P90( will require drilling 2 2.5mm holes in the P90 body) and the other is for the pivot of the mag release lever. It is also designed to use an M5 dog point grub screw in the back of the adapter to help with magazine compatibility and make the magazines snug. The only other hardware is a spring for the magazine release lever, I used a V6 gearbox cuttoff spring because I had one lying around but can be any small spring that you have lying around and is 3mm or less in diameter. Designed and tested with PTS EPM-1 mags. Have tested ARES, Cyma and G&G mags and they all fit, the Ares ones are tight on the mag release though. This was designed as a way of testing my high rate of fire P90 because the standard mags wouldn't feed fast enough and was never meant as a proper product. The end result was surprisingly good though and because of popular demand I have shared these files.
