I'm considering building a 300 blackout pistol and have some questions about the 80% lower.

My bro built one other day. He said it took him a little time but wasn’t much to it. And he had no YouTube tutorial working for him.
He got a shooter. Anderson ghost lower. PSA upper. He had 3 you could cover with dime.

On the distance I like to walk to my stands:

Uncut lower -check
Drill press - check
Xy axis DP vise - check
Decision on jig - Nope can’t decide
Stuck in place - check

Decision on jig - Nope can’t decide Have you looked at this? >>>-------> https://www.80percentarms.com/colle...asy-jig-gen-2-combined-ar-15-and-308-jigI'm thinking real serious about buying one. Get a free lower with it.
I firmly believe that a double gallows should be constructed on the East Lawn of The White House. Politicians who willfully and shamelessly violate their oath to uphold and defend the Constitution of the United States of America should be swiftly tried and, upon conviction, publicly hanged at sunup the day after conviction. If multiple convicts are to be hanged they can choose with whom to share the gallows or names shall be drawn from the hangman's hat to be hanged 2 at a time.

This higlights my issue. The DP is neither the best tool for the job nor really a good one but I have one. The best tool is a mill (too expensive and don’t have) with a good alternative being a router with an easy jig or equivalent. Less expensive but still don’t have and some require proprietary end mills.
If I wanted to do more than a couple I’d prolly go the router + easy jig route. But having the drill press makes me a sucker for going cheap.

I have a floor model drill press as well but I believe this jig may be easier with a router and I have a router.

I've done several AR15 lowers as well as a couple of AR10. I use a drill press with a XY clamp. I first bought a polymer lower to practice on. You can get one for about $20, https://www.eparmory.com I also bought their jig and works good. After the poly lower turned out fine I started doing aluminum lowers. If you can find a lower made from 6061 aluminum it will be much, much easier to work with compared to 7075 aluminum. The 7075 is some really hard stuff and can be a pain to work with. I've done a few with 7075 and it's really slow going. A 6061 lower I can finish out in a couple of hours, 7075 takes me all day.

If I agreed with you, we'd both be wrong.

Less than impressive first 80%er. Drill press is NOT the best way to go. It was cheaper but tough on the DP and the end mill. Now if I can find a 350 Legend upper I’m a gonna bust a cap on a hog or two. Cause I can’t find no deer to do it on. Edit - Not standard mags! Forget that chit. 350 legend misses the point. Finally hogged one out
