[ARCHIVED THREAD] - CMMG upper and other lowers

Posted: 8/1/2009 12:45:26 AM EDT

I have a CMMG upper, it seems to fit very tightly on 3 different lowers I've tried it on. Is this normal? It did not need brute force or tools, but a lot of effort nevertheless...is this normal?

It can happen. Nothing wrong with a tight fight.

To a point, that's a good thing. Less Rattle. You can always make it looser, but as long as it doesn't take 2 people to close it up I wouldn't worry.

well, it doesn't take two people to put on but it it very tight. If you undo the rear pin the lower will only hinge down a bit, not all the way to 90 degrees like the M-16s I trained with.

Will it loosen up a bit by shooting? I only want it slightly looser...

This "too tight" is self-correcting. After you've fired it a while, and opened it up to clean it a few times, it will be easier to open. Eventually, it'll be smooth and effortless. It just takes some time.

Thanks,

that's the kind of "fix" I like to do...
