I have a JG AUG A2 that is absolutely amazing apart from the front grip which is wobbly and unpleasant to use so I was considering replacing it with a rail section however all A3 conversion kits seem to be sold out everywhere I look and I don't own a 3D printer. The included image is the kind of rail i'd like to attach if i can't get a JG A3 conversion but I also cant seem to find something like this either. If anyone knows any places that sell similar rail sections that would be a great help.
