Running this with Mean Arms Endo mags. Bolt chewed up the plastic ejector on the mag inserts causing ftf issues. Otherwise very pleased, accuracy is very good. To be fair I'm new to the pcc game.

Awesome for the price
With the rage of 9mm builds right now this amazing piece was a great price. I believe the handguard is a JL Billet piece it looks very very similar to my JL logo'd handguard. I assume its a custom made piece just for PSA. Everything looks good have not fired it yet as I just got it today. Amazing deal I would say. I paid 229$ with free shipping. PSA does great stuff.

Well pleased.
I have this upper mounted on a PSA pistol lower and am very happy I bought this. It is well built and I couldn't find a single flaw on the upper or the lower. I put a Magpul Sling on it and adjusted it to add stability while pushing the firearm away and it ran like a champ. I've only got about a hundred rounds through it so far. I shot Federal 115 grain FMJ RN some of my 124 grain FP reloads & Hornady 135 grain Critical Duty rounds. It fired ejected and fed all of them. The only improvement that should be made is getting the bolt to lock open on an empty magazine (I knew about this before I ordered it so I wasn't expecting it to lock open). Thank you PSA.

Had some issue that had to be taken care of
Love the look and feel of this upper. I had a SBR for this. First before we ever fired it we noticed the BCG just was not sliding well would stick. Decided to try it out as we had a demo with it coming up for some customers. It fired but the KAK on the end actually fell off!
Customer service was helpful and we sent it in. It came back very quickly. Looks like they just ground the BCG a little (maybe dremel) and not sure how they got the KAK on because it seemed stripped before. I wanted to take it off and see if was the same one just loctited on heavily but dare not.

I was a disappointed that they did not replace the BCG or the upper as it had a couple things wrong with it. Shot fine though just seems a bit "rigged" was to address the issues.

I am a dealer and manufacturer and have always had a really good experience with PSA however this one left me a little less than pleased.
