Guys, I was finally able get out and test one of my latest AR builds that has a PSA 16" Carbine Length 5.56 NATO 1:7 M4 Nitride Freedom Upper assembly. This one.
It shot very well. The Primary Arms SLx Advanced Push Button Microdot Red Dot Sight zeroed easily (@ 50 yards) and the MAGPUL MBUS Rear Sight required no adjustment. I am very pleased with this upper.
