Lower to Upper clearances (problem?)

[ray1970]

My backup plan is picking up a Noveske Chainsaw lower.

Just keep in mind the chainsaw lowers are blems. Probably for cosmetic purposes but you never know. Personally, I'd spend a few dollars more on one that met their quality standards and didn't get marked as a blem.

They will say it's the upper and not their lower TacIN has always been good CS wise. They took care of an issue i had with some browning bbls, didn't care how many rounds fired they wanted to make it right.
FWIW: Both my Colt & LMT Factory AR's have some slop. Fortunately i am not That Anal and only concern myself with COM out to X yards. I have also seen "on line" (surprise) a co. that was offering "shim" kits to eliminate s-s play between upper & lower. IF TACIN does not help you this could be Plan B.

Nice Jim, thanks! I think I'll try this first and see how it goes. $17 is better than $200+ for the Noveske. And like what Ray said, Noveske may not fit tight either. My wife was going to buy the Noveske lower for for Christmas but I still need a BCG. I'll tell Santa I need that instead.

Along the same topic, I have an LMT upper on a PSA lower that fits so tightly I have to tap the takedown pins out with a hammer. I put that LMT upper on a spikes lower and it rattles all over the place.

^ always the case w/ certain lowers. Cav Arms, rainer and PSA lowers are always tight for some reason.

I have a TI T-15 lower and its nice and tight. Its not a billet lower though.

Hence the term: "Mil-Spec". Basically means any component from any contractor will interchange.
In more basic terms it means tolerances you can throw a cat through.
When you see "matched reciever halves" it just means some grunt is making 8.00 with a pile of uppers and lowers "fitting" them.

He knows someone, who knows someone. Hopefully one of them is a smith.

Cats are a multi-purpose tool Ray. I have a Cathead for my lathe too.........
