I did email m60joe and mailed him a lower to mill out. He said it might be hitting the back end of the receiver. So I will have to wait awhile more to find out if that was the problem. hope that fixes that. I also got more paddles of different sizes just in case.
I also got a h3 buffer just in case I get bolt bounce. I may need more as I have 4 diff uppers and a few lowers. 3 of the uppers are left handed so we will see how that works out(7",11.5",16"). And I am looking at getting the AR47 lower.
I did get a new in the wrapper RLL, which was not that much more than a used one.
This was a long wait as it went pending in Jan. and did not get approved until May. ATF ask for a copy of Trust two times.(I am guess they lost it)
