Great upper
Fired well over 300 rounds in it so far and not one hiccup. Really likes the 62 grain ammo. Nice groups at 100 yds with it.

Good Upper
The upper is a quality piece of workmanship. Looks great and functions well. However does occasionally short-stroke on some ammo brands. I suspect the dwell time is a bit short on the rifle length gas system. I would, still however recommend it.

Bad experience overall
First off, let me say that I have been in retail management for over 8 years so, I know all about customer issues, bad/defective product and the general craziness that comes with being a retailer. And it has made me a very understanding customer.

That said, dealing with PSA on this purchase and the subsequent issues was one of the most frustrating things I've ever experienced from a retailer. When I first received this upper, I noticed that something wasn't right as soon as I opened the box. The handguard took a noticeable turn upward from where it met the receiver (see the pics). Long story short, no amount of adjustment I could do would fix the problem and there was no way to sight the rifle in with iron sights due to the angle of the handguard. Besides, it just looked bad. So, I contacted PSA and they had me send it back for repair.

I received it back in about 2 weeks only to open the box and find that, not only was the handguard still out of whack but it was noticeably beat up as well. Granted, it wasn't intended to be a presentation piece but I would have liked to put the first 4 scratches and dings in it myself (and if the handguard issue was fixed, it wouldn't have bothered me). So, I contacted PSA again and they told me that if I still had issues with the upper that I should send it back for a refund. Not a replacement, not a fix, not an upgrade (I offered to pay more for a different handguard)...just a refund.

That kind of customer service tells me a couple of things...they don't stand behind their product and the defective product they sent me was the best they have to offer. So, I sent the upper back for a refund which led to yet another issue with PSA. They had the upper back for a full 2 weeks and hadn't given me my money back. During that time, I emailed them asking for an update and never received a response. Then I called them and was told that they would process it when they got around to it. When I told them that I was going to dispute the charge, they gave me attitude (God forbid I want my $380 back, right?!). The next day, I received an email saying that I had been credited for the refund but it still took another week before it hit my account.

So, that's it. Proceed with caution. I had ordered a few things from PSA before and all went well. And I have a bunch of family and friends who have ordered from them in the past. I've let them all know about this experience and they've started buying elsewhere on principal alone. Bad customer service has definitely lost PSA some business in this case.

Sorry for the long read.

This is an absolutely beautiful exquisitely made upper and with a nickel boron bolt carrier group. Couldn't be happier with the quality or the price unbelievable! PSA never ceases to amaze me with their prices

Shoots great, about 100 rds. so far. Just under 2 in. groups @ 100 yds. Good enough for a ground hog @ 70 yds. and a coyote @ 120 yds. Very pleased.

Nice Upper
Fit and finish very good, shoots very accurate with out break in. Only one dislike ... that's the M-lok configuration. First M-lok I have owned, the rest of my MSRs sport the Key-Mod which I like much better, the M-lok IMHO is a pain in the butt, however to each their own. Yes I would recommend to all others.
