I just ordered a 7" bbl upper. Fist, thanks for the 1/2-28 thread pitch! That simplifies it a lot for me!

Looking at the pic, I don't see the cut out for the ambi bolt release, and was wondering if in fact it has it.

Here is a screenshot of what you have posted.

I'll make it work either way.
Thanks

Shoot straight and tell the truth!

I saw that one of them had a slot then the other two, the 5" and the 7# did not, that's why I asked. I'll just grind my own slot. Thanks.
