Allows for a MP7 springer to receive MP5 AEG mags. (Because its what I have)

PETG or similar, 0.4mm nozzle, 0.2mm resolution, clean the long feed tube of the adapter after print, some material catching the BBs on the short tube is fine as long as they can be pushed through with little force (catching on the small tube will eliminate double feeding).

Simply take the mag release pin out, remove the body screws, pull back the cylinder, insert the adapter, and finally reassemble the gun.

If you were to remix this design simply credit me.
