Made a mag adapter for airsoft G36 and SL9 to work with M4 magazines. Print with supports enabled. There shouldn't be any support structure in the feed tube.The support structure around the mag release can be difficult to remove, don't cut the pivot point on the release and do not insert a mag until you get the release to move. The file with the U should work with Umarex and the one with JGTM should work with JG or TM compatible, they're both close but have minor differences that mess with bb feeding. I tested them on a Umarex SL9 and a JG G36K.
