AR Wobble!!

The old colt uppers had a bigger pivot pin. You need an adapter for it to fit right on a later model lower.

Ok who makes them and where can I get one?

Whoops, wasn't paying that close of attention. Maybe a rubber gasket could work. It'd wear out but would be a cheap to replace.

I looked it up and it's only really for the rear pin, I need something to make an Old Colt upper work on a new AR lower

Its called an offset pin. There are around 4 - 5 $.

Nah that won't work, My upper is the one with the BIG hole and the lower has the Mil-Spec.

That part is for Mil Uppers and Colt Lowers

NOOOOOO Don't buy an offset pin! That's to make a new upper fit an old lower! You need the opposite. It's just a little tube shaped adapter and the standard pin for your lower goes in.. I'll find it ...wait a minute!

I am not 100% positive that it is the lower in this case but could very well be. The lower that you have was made by a company called AR 57, I think that is correct. They started making their lowers right around the whole rifle scare came about. Well they had many many poblems with them. I bought two lowers and had to send them back 7 times before the ones I got were in spec. I was not the only one, their were problems with everyones. I would research and see if your serial number matches one of those. I do know AIM surplus dropped them and I think they stopped making lowers. My advice, take that lower back and get another brand.
