    How difficult is it to finish an 80% lower? I was thinking about getting one to build another AR, but was not sure if I would be able to finish it. Any help would be appreciated.

    There are several threads on it already. But you'd spend an eternity and be lucky to get it done well enough to function. I've heard of some using dremel tools but they never look all to well and most times have poor function. Some use a drill press experience some success, most need a mill

    Thank you. I don't own a mill and don't want a half assed gun so I won't go that route!

    Yeah mine is still a paperweight for now. I need to broach the magwell and finish the fire control group cavity. Don't have the tools I used to and you DO have to finish it yourself. I hang on to it because you never know, also it was very cheap and is very cool - an old Gen 1 Sun Devil 80% lower with carbine stock kit, all camo'ed. Years ago a manufacturer used it to display uppers.

    Heh, I looked into it myself. I spent endless hours reading. After you bought the jigs, ruined a couple 80%ers, broke some drill bits and the rest of the crap that would occur, you could have probably bought a DD full unit. Besides, if Quen hasn't done it, I wouldn't even attempt it.

    The magwell isn't hollowed out and needs machining to remove the metal.

    I recently ordered an 80% from Ares Armor. Magwell is finished, all tapping done, and it's anodized. It needs the fire control pockets milled, and 3 holes drilled, I think. I have access to a bridgeport W/DRO, (hopefully, no jig will be needed) and a lot of skilled people, and a little machining experience myself. I consider myself to be barely capable of finishing this project.

    I think you are referring to a "0" percent lower. All of mine came with the magwell cut out really nice. But just like you, not had the time to fool with it. Was going to start one about a month ago, but life happened:( :(

    I thought there was a version with out the magwell machined. Then they changed it to leave only the easy parts......

    All of the above is true but one important detail is omitted. When it is complete you have a lower with absolutely no BATFE paper work and as such will be "off the grid" and hopefully safe from a gun grab. As long as it remains off the grid. To me, that possibility alone makes it worth the effort and possible cost.

    ^^^Yeah, +1

    Just wondering....could you imagine a situation where it would be "on the grid"?

    As long as its existence is shared only with like minded people, it should be safe. As soon as a gun hater or someone who is envious because they lost their gun to a confiscation gets wind of it you become a target. I would imagine that it must be treated as an "ace in the hole", so to speak. So it can be used if and when its usefulness out weighs the possible penalties involved in its discovery.

    Yeah I really don't know what percent it is but it's closer to 80% than 0. I doubt I'll ever finish it since I don't need it.

    Might not be a bad idea to start getting the stuff to do it just in case

    I get the "just in case," however do you know what a mill costs? Don't get me wrong, there are many things in life I choose to do half-assed , but I don't think I want a half-assed AR in my hand that might get the wrong kinda boom when pulling the trigger..... :eek:

    I agree. But I'll probably wait since it doesn't have to be done right now considering I already have four complete lowers to three complete uppers. If and when the need arises I'm pretty sure I could do the job. I've always been handy with my hands and tools.

    Also since it is stocked, it's kinda cool to push in the pins to a complete upper so you have something that really, really looks mean yet isn't even a firearm! :D

    The milling adapter kit at CNC guns makes it possible to do it with a drill press and a dremel (actually there is a youtube video series where a 40+ year old guy who looks like he lives in his mothers basement does it)

    Takes a lot of time, but it can be done.
