psa 16 inch upper
installed on a franklin armory lower with a binary trigger functions flawlessly and accurate

Ok quality!
The price was nice and the fun shoots well. The only issue I’ve had with this is the front sight tower is crooked, it is canted slightly to the right. I have no attempted to straighten it yet due to planning on mounting a scope and eliminating the front tower eventually. The second issue was on the BCG, the firing pin cotter pin would not seat all the way in so the head of the cotter pin was rubbing in the inside of the upper. Other then that, everything has worked great with no malfunctions.

Excellent upper
Dare I say I don't even look at other brands anymore as PSA has supplied some excellent uppers and this one in particular lives a tough life as a truck gun, runs all sorts of ammo and doesn't complain. Quality is excellent and performance is excellent. Plus the warranty is phenomenal. One tough and reliable upper.

Very good upper for the money.
I installed this upper on a budget lower that I had previously assembled. It shoots under two inch groups at 100 yards and has been very reliable.
