Was drifting around on YT and stumbled on this.

So that is how you finish a 80% lower. With JB weld. And a pink rattle can.

He said he used a "sticker jig"... I looked it up and it is stickers that cost $4. Maybe he will get the proper drill jig and bits for the next 80% project. I'm sure he will do better on the next one. I had thought about getting a few 80% lowers for myself but ended up buying 3 lowers from a local manufacture after watching a few YouTube videos.

A "sticker jig", now that's some precision tooling. I've finished six 80% lowers and have two more I plan to finish when I get inspired to do new builds. They all function as they should, but the first two needed some "minor adjustment". It's not that difficult to do with a good jig and having a drill press also helps. However these cost more than $4.00.

The color suits him. He has got to be an eggspurt!

I think he posted it because he wanted someone to help him "fix" it. Does JB weld even stick to polymer worth a dam?
Dull tooling just melted that plastic crap. "But it looked easy on you tube"

I am a 45 year machinist, with Bridgeport, lathe, surface grinder, etc. I have done one 80% and it was perfect when finished, but I agree that it is more trouble than it was worth, and less expensive in time and money just to buy a decent lower.

That kind of workmanship on a rifle purely makes me sick.

Maybe if he gets a few more poly lowers and practices a lot, he might be able to make a serviceable unit, but not that one.
Somehow, I don't think he was looking for a challenge, he just wanted a ghost rifle, Cheep!

Yeah sure go with an 80% lower when you want 50% reliability or in this guys lower zero percent reliability

I want mine to be yellow and say "TONKA" on it.

my 20 inch grendel is on an 80% lower no problems what so ever, i bought mine to replace an oem lower i had it on well mainly cause a skelotonized lower isnt cheap lol and it was something to kill time with lol

[JTB]

I hope he cut that thing up or melted down or something. I never in my life lol
