Its frightening the amount of failed 80% builds there are out there.

Looks like a bunch got tossed in a drill press with some DeWalt drill bits, builder tossed a couple cocktails down to muster up the nerve, and these are the results.

I've seen horrors... horrors that you've seen. But you have no right to call me a murderer. You have a right to kill me. You have a right to do that... but you have no right to judge me. It's impossible for words to describe what is necessary to those who do not know what horror means. Horror... Horror has a face... and you must make a friend of horror. Horror and moral terror are your friends. If they are not, then they are enemies to be feared. They are truly enemies! I remember when I was with Special Forces... seems a thousand centuries ago. We went into a camp to inoculate some children. We left the camp after we had inoculated the children for polio, and this old man came running after us and he was crying. He couldn't see. We went back there, and they had come and hacked off every inoculated arm. There they were in a pile. A pile of little arms. And I remember... I... I... I cried, I wept like some grandmother. I wanted to tear my teeth out; I didn't know what I wanted to do! And I want to remember it. I never want to forget it... I never want to forget. And then I realized... like I was shot... like I was shot with a diamond... a diamond bullet right through my forehead. And I thought, my God... the genius of that! The genius! The will to do that! Perfect, genuine, complete, crystalline, pure. And then I realized they were stronger than we, because they could stand that these were not monsters, these were men... trained cadres. These men who fought with their hearts, who had families, who had children, who were filled with love... but they had the strength... the strength... to do that. If I had ten divisions of those men, our troubles here would be over very quickly. You have to have men who are moral... and at the same time who are able to utilize their primordial instincts to kill without feeling... without passion... without judgment... without judgment! Because it's judgment that defeats us.

I recall James Yeager

making a video mocking folks for doing 80%s (he did say he wasn’t referring to people who actually know how to machine shit), and this is the result he predicted.

My 80%s are beautiful and dimensionally perfect, but I’ve spent a lot of my life doing shit like that with aluminum.

If not using a jig, at least use a drill press.

That wasn’t a good period of my life, I was trying to recover from watching an entire 50” nutnfancy video and swung too far the other way

I may also have the entire set of the Magpul Art of the Dynamic fill-in-the-blank DVDs.

OP, next time put a warning on the subject line.

Can't think of the last time I winced so much when scrolling down.

I mean, are these guys trying to use a drill press while their buddy is just hand holding the lower?

I surmise that there are probably 50 untouched 80% lowers for every one finished and for every 3 finished with some degree of competency that at least yields a functional firearm there is one like there where someone just said fuck it,I'll eyeball it and use my cordless drill.

Guns are like everything else. There are car and carpentry projects finished to a high standard of workmanship and then there are horrible hackjobs that end up just being scrap with a bunch of stuff somewhere in the middle.

I have a bunch that I’ll never touch for this reason, even with a mill

*raises hand*

M16A1 lower done by Braceman for my Mk12 Mod H clone. The serial is actually my mother's birthdate (she passed away) so I've been dragging my heels a bit to make sure I do it right. I have the jig, I just need some time in a machine shop and not be rushed.

Uh-Oh! Looks like pic #5 was going for a full pocket M16 profile.

I hope he can finish that Checker's/Rally's burger before the ATF kicks his door in!

I'm guessing the guy who made this monstrosity Glock upgrade probably is responsible for some of those 80% pics...

What's really funny is how many of these FUBARs still work just fine.

Hell, I converted a (surplus, stripped, pitted, get off my ass you tools) M1 Garand receiver to BM59 specs using a Dremel. Magwell interior is a bit wavy, but works just fine.

No, I've been privy to all of this site's wonderful hypocrisy and lack of integrity for quite some time now.

I'm still just dumb enough to point it out.

I have a failed 80% lower. I wasn't paying close enough attention and the depth stop on the shitty drill press I set came loose and lowered itself down and I punched right through the bottom of the trigger pocket

I did the rest of mine on a 5D Tactical jig using a router and they came out perfect.

I laughed when that video made the rounds.
I made the President’s Hundred with a lower I milled, engraved, and anodized in my garage.
