Machining metal frames/recievers
In light of the recent retailer closures, I've been thinking; since the only restricted parts would be the frames and upper/lower receivers, couldn't we make our own? I don't have much machining experience apart from some high school CNC courses but I'm pretty sure that a 3-axis mill will suffice for most parts. So far, I've tried and failed miserably to cast an aluminum frame for a friend's Kraken. I'm not too clear on the legalities at the moment so I'm not gonna say. It's just an idea...
