Airsoft M4 to Arp9 Adapter

thingiverse

I made this to fit any m4 mag well for a 6mm airsoft rifle. It only needs 1X 3m screw to secure the lever into the mag adapter. The spring on the top of the arp9 mag (bb securer) should be enough tension to keep the mag in place once put in the adapter. I recommend using tree supports. and print it on its side. it will be stronger if you do and you will avoid snapping the front piece off. put support blockers on the inside of the bb feeder rims.
