I ordered 2 uppers from PSA during the Black Friday sale. One of them shipped out quickly, the other one didn't come until after Christmas and numerous emails to the company. After the late one did finally show up, they sent incorrect parts with it. I ordered the upper and a complete Magpul MOE lower build kit and they shipped it with a pistol buffer tube.
After numerous emails back to PSA, they did finally send me the correct buffer tube.
That one is over with and shoots just fine. The first upper that I received quickly has something wrong with the left side feed ramp. Every single round jams on that side. A pull and release of the bolt will usually slam it into the chamber. After firing, it slides right into the right feed ramp, fires, and then jams again. The bullet nose gets stuck between the lug slots. It looks like it might be a burr or something as it's actually cutting into the copper on the bullets. I've tried to contact PSA several times on suggestions or if they would like it shipped back for analysis. They will not respond. As of right now, I'm stuck with an upper that will shoot 2 rounds at a time.
I'll probably drop it off at a gunsmith to have them fix it, but I'm infuriated that PSA won't respond or stand by their products. I spend about 15k per year on firearms, and I will NEVER buy from them again. I'm glad that others have had good luck. Mine has been terrible.
I'll stick with Daniel Defense, BCM, and ASA.
