Airsoft Hi-Capa 4.3 Rail M4 Mag adapter V2

UPDATE: V2 has been added. This just splits each side into left/right side & left/right clamp. This allows easy attaching and detaching. Other than that it is the same as V1.

I haven't tested if having one side V1 and the other side V2 works, but theoretically it should work. 

Update over

This is an M4 mag adapter designed to fit a Hi-Capa 4.3 Rail. It might fit other rails, but this was the rail I had available. This adapter works with PTS EPM Mags, but might not fit other mag types without modifications.

You'll need to sacrifice a 5.1 Mag with a thick bottom plate for this and cut a part of the bottom plate out to make room for the bb path. You'll also need a single stack print. I've added a 5.1 and 4.3 mag single stack here. The main difference is the length of the wide open part at the front of the mag. These parts will need some sanding to fit, as they need to fit snuggly.

You'll need some M4 and M3 screws. Two flat headed M4 screws (roughly M4x25, I cut M4x30 down to size), 5 Angle Headed M4x16 screws, and one angle headed M3x30 screw. And a corresponding nut for each screw. The M4 screws will need to be cut unless you can find some that have a perfect length.

You'll also need 3 springs. 1 for the bb stop and 2 for the mag release. These are just regular ballpoint pen springs.
