You're taking a gamble.
I am one of the unlucky few who've had problems with my PSA product.

I ordered this upper 4 months ago, in the time since then, I had to RMA it once and im waiting to RMA it again now for a second time.

The first time it was cause the guys at PSA torqued the barrel nut down to 9999ftlbs, so I had to return it for them to loosen it, even my local gunsmith couldnt break it loose.

The second time is now, I literally just got back from the range, finally got time to take it out to shoot.. and what happened?

My extractor is ruined. I didnt even get to fire a single round. The first round I chambered jammed up, appeared that the cartridge didnt seat fully in the chamber, and the weapon was stuck out of battery, this happened 3 more times before I gave up. Attached are images of the bolt head and the malfunction I was cursed with and could not avoid.

Loved it!
PSA service was excellent. Ordered and received in less than 1 week. The upper was extremely nice and fit perfectly on my PSA lower. Shot around 120 rounds with zero issues. Will definitely buy PSA products again.

Nice build
Great upper receiver. Just like advertised. FYI it will not fit an mlok rail at the 9, 6 and 3 o'clock position forward end due to clearance with the flash can and does not come with the flip-up sights. Mine did not at least. 300 rounds at the range with no issues.

Great upper! Shoots great and compact!
Love it! Shoots great with my SB adjustable brace. Thought it might be loud but can’t say that I noticed much difference from my 16” AR.
