I'd really like to not pay $300 for something that is going to get used once. I had originally planned on building several G3 and MP5 clones, but parts kit prices have squashed that idea. I tried to find the diagrams online to just make my own jig. and I haven't had much luck their either. So I've got one lonely G3 parts kit that I need to put together, does anyone have a jig I can borrow or rent? I'd appreciate any help I can get.
