While I don’t own a firearm, I’ve always been intrigued by the incendiary topic of Ghost Gunner. Basically, they sell a CNC machine ($2K) for a private US citizen (in most areas) to legally finish producing their own firearm by milling the last 20% of an 80%-complete “lower” of an AR15 (and you buy the other pieces of the assembly for a full-working model). They, of course, sell the 80% lowers made of 7075 billet aluminum. I know very little about weapons, but I gather the “lower” is what’s needed to tie all the other purchasable pieces together and make a working unit. Evidently, this dodges some sort of regulation, but I haven’t reviewed the legalese on what that exactly is.
So, has anyone looked into and/or knows the trade well enough to know if the MPCNC (probably a smaller one) can operate at the tolerances required and leverage the digital files to finish producing the “lower”?
We’ll I didn’t exactly do a lot of research, but after looking at a few videos the milling apparatus is oriented to a different axis than a MPCNC, so I imagine there would be a lot of pain/trial/error getting that to work. Looks like a no go.
