I'm in the process of designing & manufacturing a .45 caliber semi-auto carbine, and it occurred to me the other night that it would not be difficult at all to off this as an 80% kit instead of a finished rifle.
I'd only leave material that would be easy to remove with a milling machine, requiring no complex or heroic setups, exotic tools, etc. Probably do the bulk of it with a single 1/2" two flute endmill.
The bolt, extractor, ejector, barrel, and muzzle brake would be 100% finished, so you wouldn't need to know how to thread on a lathe (or even own a lathe) or chamber a barrel. All springs & hardware included. Magazines would be included too, so you don't have to mess around with them.
You'd have to pocket out the FCG area and the magwell in the receiver, cut the cross slots on the rails of the chassis (the chassis of the rifles will be an extrusion that bears the profile of a mil std mounting rail on four sides, but you'd need to cut cross slots wherever you want them), and drill the butt plate to accept whatever butt pad you want to use.
The majority of the carbine will be made from aluminum. All the parts you'd need to do machine work on would be aluminum. There is no wood. It uses standard AR15 FCG parts, an AR15 pistol grip, and M3 Grease Gun magazines.
I don't have a solid price range yet (not far enough along to put a number to it), so please post your personal opinions on price range when you reply. Say what the most you'd pay is, and then say what price you'd need to see before it would go from a "Maybe" purchase to a "Hell Yeah" purchase.
These are early days, I'm just trying to get a feel for whether this 80% kit idea is any good or not.
Thanks for your time guys, I appreciate your input.
