NO. You can screw up a rebuild on an engine, trans, wheel hub, etc...do the same on an automatic AR-15 and you risk losing your hands or life. I would be like, "hhmmm, never built a pipe bomb before to get rid of that stump, I'll just throw some black powder into this pipe, tamp it down nice'n' compact with this metal mallet..."
NO, no, no. Find something else. Like, if you can build an E30, why not an airplane for you and your family??
Seen too much of this type of thinking splattered all over.
um, okay, first of all, AR-15s are not fully automatic, they are semi-auto only unless you have a ton of money for the tax stamp and all the paperwork to make it legal, in which case you'd probably already have the money for an LS1 E30... EDIT: you don't think he can put together a gun that grunts have been taking apart and putting back together in the field for over 40 years now, but you suggest he build an airplane? for he and his family?
in building an AR you can decide to do as little or as much of the work yourself as you want. you can buy a complete gun, the upper and lowers already assembled and simply attach the two, or you can buy each and every piece you need separately, or if you just want a basic first gun, there are gun parts kits that have everything except for the stripped receiver included. the receiver is the only part with a serial number, so you have to do the federal background check like any other gun.
for my first gun, i bought a complete lower, and complete upper, as there are some specialty tools, but also supposedly the gas port bolts on the bolt carrier have to be staked properly or you can have reliability issues, or things coming apart while you're shooting. you could get around this by buying an assembled bolt also.
i like the versatility that the AR platform allows, i can use the same lower receiver and simply swap out mags and upper assemblies to shoot 22LR, .223/5.56, 7.62x39, 6.5 grendel, 6.8 SPC, 450 bushmaster or even .50 beowulf. there are also a couple of pistol round conversions that use a magwell block and stick mags from an uzi or similar to shoot 9mm, .40cal, or .45ACP.
i posted my "build" a few months ago in the "craigslist for firearms" thread, but it appears my host has died. i'll try to put those pictures up on my photobucket in a few. feel free to PM with any build questions you might have.
