    I'm new here and was wondering if anyone has ever machined a 80% lower?
    Just wondering what is involved or where to bring a 80% lower to have machined? Thanks for any help it tips.

    I'm looking into this myself.
    There are a few videos on youtube. Seems easy if you have the right tools.

    For the most part, I think all you need is a drill press and a jig.

    I would also love to hear anyones feedback on this!

    If I remember correctly, you can't have someone else machine it for you, it has to be done by the end owner. I looked into it myself and as Nosmoking said, it supposedly can be done with a drill press and the correct jigs.

    Not to scare you off, but here is some insight into finishing an 80% lower from TonyRumore (invented the Tromix S17, the original 8" barrel Saiga-12) and TapeWorm3 on the Saiga-12 forum:

    You must mill the pocket for the trigger group and locate, drill and ream a few holes. I would not recommend this unless you have a machinist to walk you though this step by step.

    They only take about three hours each if you have a mill and the correct tooling. My buddy and I just did a few. I am looking to get a few more to build some for the kids.

    Which translates without the right tools/jigs and first time doing it you'll be ripping your hair out in no time.

    had build parties in CA, great way to build an untraceable rifle, a little involved but not actually too hard.
