AUG Front Grip Adapter

I made this AUG picatinny adapter for my airsoft AEG AU-3G by Jing Gong, i don't have a clue if it wil fit on other brand AUG airsoft replicas, or even the Real deal one. I needed to do a light bit of filing on the hole to get an M4 Hex screw through there. yours might also need it. If anything is wrong gimme a heads up, and im always open to feedback! I also provide the .f3z file so you can edit it all you want. -GL!
