And even my 6.5CM upper shows that gap... and shoots shockingly well.

Full report over here...

Thanks for the link, when I get a chance I’ll look up what those links are, the site doesn’t show what they are so I’m not going to spend money until I see the product.

I did jam a wedge in there, got it snuggled up.

For those that say it’s no big deal to have some slop, I disagree.
It shows poor quality control.
No other AR I have or any of those I looked at this weekend have a gap running the entire length of the upper/lower like this does.
A little rattle is one thing, seeing a gap running the entire length is another.
Just poor quality...
