Mag issues
Overall I really like the way the upper and lower cane together. At the moment I am having some feeding issues with factory magazines. The bolt has damaged the feed lips on two mags now stripping the metal insert down and into the top round on the right side of the mag. I have bought new mags to see if the problem persists and will follow up with PSA if it continues.

Solid upper assembly
Very nice fit and finish. Have only run around 100 rounds while zeroing, and am pleased with the accuracy and performance. I was a bit concerned as the the design of the feed ramp, but seems to function properly.
Also purchased the matching lower from PSA at same time and am waiting to rate same as there was a problem with failure to eject and feed jams. Had to tweak the ejector assembly to get the appropriate positioning to obtain proper alignment to eject spent cases. Thereafter ran the 100 rounds with no further issues.

Great product!!
Awesome purchase, I have not had any issues at all with this barrel, it shoots very straight and looks great. I will definitely be buying another one in the future. But nothing is ever perfect so that leads me to ONE detail I found that wasn't 100%. My firing pin wasn't perfect, it wasn't completely true had some weird grooves on it. It in no way caused any issues with running it but I did feel it needed to be swapped out. Otherwise no regrets.

Build your own, more fun, more reliable.
Being generous with a 3. Got this and was going to put a 16” barrel on it, but some goof ball over torqued it and bent the upper a bit. Took it to a gunsmith to have the problem fixed and the barrel taken off. They put some type of locking liquid on it, needed more than a heat gun. PSA said send it back, but I would have to wait another 2-3 weeks. I would prolly build my own before I would buy another one of these.
