    I thought about doing an 80% lower, but decided against it based on the cost of the jig.

    Good luck, but I'd spend a lot more time and money for materials than it would be worth to save the $100 for the price of a new, mil spec lower.

    Oh, well then by all means go for it. Building shit is awesome and fun, as long as you aren't expecting to save money :o

    Yeah I doubt I could beat $105 for an EA lower, especially considering the time spent. I have access to a machine shop and nothing to machine.

    Form 1 a suppressor. They are fairly easy to make, and it will actually save you money.

    or you could thread my barrels for cheap :big grin:

    done a 0%, but it's real pain in the ass without a jig or a CNC machine. Use a surplus mill, go slow, do a little bit at a time and if in doubt, measure.

    I'd be doing this at a well equipped shop. Family friend used to make parts for a firearms manufacturer (or so i've been told). So that should help :o

    I'm just kidding man, I got a guy here that does it cheap. If I were you I'd take advantage of the shop to demil and build those AK kits. You should be able to make some rivet jigs pretty easily with scrap metal.

    There's a couple of guys over on pirate that machined their own. Somewhere out there is a site with step by step instructions on how. From what all of them said it took several tries, a bunch of time and certainly was not cheaper than buying one. However it is cool to say you made it yourself, and if you are tinfoil hat crew it is a completely off the book lower.

    I would love to try that. I have a friend with a mill (since the ones at work are off limits totally for home projects :() and this guy would have no prob with me using it, I just haven't decided to invest the time yet. I think I can locate a piece of material but it wouldn't be cheaper. If you buy a forging it comes out cheaper I think though, at about $30 each for the raw chunk. I'll have to remember where I saw that though... And you can't really count your time, I mean the cost of these things is based on mass manufacture and I would be doing it partly for enjoyment and pleasure of knowing it was made by me. Can't put a price on that really.

    Not even CNC!

    Rapid Prototyping, more specifically: Stereo Lithography Apparatus.

    The upper is a Sun Devil MFG billet upper.

    i had to have it to match the Sun Devil lower

    What SLA material is that? I have some SLA stuff but none of it is that clear. I like SLS better but the resolution isn't there.

    If anyone has access to a CNC I could probably knock up a CAD file of the receiver to start programming off of. I know this is most likely available on the interweb but if need be, I can make it happen. ;)
