Front Sights/ barrels canted to the left of center line .
I bought two rifle kits I matched them with Anderson lowers. Both rifle will cycle any ammo put through them however one of them had right move rear sights to the left halfway through the adjustment to sight in at fifty yards the other rifle rear sight is all the way to left to hit targets at fifty yards! Inspection of both weapons shows the barrel is turned slightly to the left causing the sight problems one is worse than the other ! Probly gonna try to send the worst one back for replacement

Can't beat it for the money
The enhanced trigger was a pleasant surprise, overall, what more could you ask for in a kit?

Good value for the money. The EPT trigger is worth the little extra. The Magpul MOE Stock is loose, but that is common for the entry level stock. Wish they had the kit with the Magpu CTR MOE Stock.

Overall, I was very please with my first range day with the gun. Built another one for my Dad.

Great first build kit, would recommend to any new builders!
This kit was a great kit for my first build. Everything went together perfectly and a day later I was out enjoying my first ar-15 on the range. So far I have 620 rounds(brass and steel cased ammo) through the rifle, and I have had 0 malfunctions. Overall I am very pleased.

I got a lemon, but CS was on top of it and made it right.
I ordered this kit as a range toy. I was out late the day it was delivered so I opened up the next morning 0600. Upon removal from the box, I noticed how the BCG was very rough and dry. Didn't think much of it until I dug a little deeper. All the Magpul stuff in the box was good and in it's original packaging, the polished trigger and all the accompanying parts looked ok. The forging id mark on the side of the upper receiver was ground off prior to anodizing. The barrel didn't look like what I had ordered but it was marked correctly albeit it just felt and looked "cheap". I was willing to overlook all this as the price was reasonable considering the political climate. I paid $416ish including shipping. I proceeded to pull the BCG apart to clean and lubricate as is do with all builds. That's when I got concerned. The bolt was extremely rough and IMO appeared never to have made it to the "finishing" stage of manufacturing. There were crudely ground down high spots on the bolt guide ring, the locking lugs had poor machining marks in them and the it was not marked HPT or MPI as is should have been. Again, I was willing to try it since it was going to be a range gun, until, I looked inside the carrier and it appeared not to have chrome lining as was advertised and there were deep spiral machining marks in bolt side of the carrier. At this point, if all these imperfections were present, I figured i wouldn't even want it as a range gun. I quickly called PSA when they opened and only had a short wait before speaking to a very helpful CS rep. I explained my concerns and sent pictures. He asked what I wanted to do to which I replied I'd take a replacement. He quicky sent out a UPS label and I sent it back. I changed my mind after I had sent it and wanted a refund instead. I called him PSA and luck of the draw got the same rep. I explained that after thinking about it I had revised my decision to get a refund. He made sure that happened upon their inspection which all done quickly as well. Bottom line, I've purchased from PSA before and will again. I believe I got one that slipped through the cracks somehow. Their customer service made up for it. My first build was psa and many of my family members have psa kits and all have worked and gone together perfectly. I give my sample size of 1 a 1 star rating for quality but their customer service 5+ stars. One piece of info I left out is that a buddy of mine bought a similar kit 2 weeks prior from PSA and the quality was very good, the bolt and carrier were marked properly and machined very well. Thank you PSA for your service and I look forward to doing business with you in the future.
