Overall liked it a lot
Like it a lot. Shot well and it is very light. Did like that there was an extra detent and detent spring. Came in handy when it flew across the room. The only real problem I had was with the pistol grip. I had to use some extra washers to get it tight bolt/screw seemed to long. Thought I just might be my order but I helped a friend build the same kit and had the same problem. That why I gave the quality 4 stars. Great for a backup truck gun and first time.

Note: it does not have a forward assist deflector and dust cover.

Perfect for first build
Bought this kit for my first AR build took about 7 days to get across the country. Can't beat the price and it seems very solid. The only issue I had was the bolt catch plunger was too small and kept getting stuck in the spring. Bought a new plunger at my local shop and works just fine. I like the bare bones look of it no forward assist no ejection port cover. Can't wait to put some rounds through it.

NOT Full AUTO bolt carrier! As advestised
NOT Full AUTO bolt carrierAs advestised I don't know why the would say that. It would not even be legalIt is missing correct cuts (milling) to be "full auto". Got kit for a song and a dance so I am not bytchin.

Budget Kit that has Bang for your Buck
I bought this as my fifth AR purchase from PSA. The $299 price was irresistible! Just finished a YouTube review video with the first 70 rounds functioning flawlessly :) Pairs perfectly with an Anderson lower. It was a little rough around the edges and scratchy but what do you expect at this amazing price? Bottom line - it works. Full unboxing and review video on my YT channel.
Couldnt ask for more for my money
I have purchased repeatedly and only had one issue with a small part missing and it was resolved immediately. Lets just call it over a doz rifles kits i have ordered and they all perform as well as my colt for a fraction of the price. I will not pay to much again for an ar as long as PSA is in bussiness. Thank you PSA

Value + Quality
I bought one of these a few years ago as a build for a starving college student. At the time I used a polymer 80% lower (but eventually upgraded to an aluminum receiver). Its a solid device. Lack of a forward assist was never a problem because the thing never jams. Its so solid and reliable its practically boring. I've actually wound up selling it to a friend to make room in the safe but I would highly recommend it again if you're looking for a budget entry level AR-15.

Great kit. Inspect all parts!!!
First thing first. Inexpensive. Fast shipping. Packed well. It's a starter rifle with endless possibilities for upgrades.(Trigger first) Inspect all parts very closely and make sure they're all there. They had a batch sent out with commercial buffer tubes not mil-spec. 180 rounds without one issue.

Great kit Great value!!
I ordered one of these as I had two PTAC blemished stripped lowers that I had recently ordered. The lower and upper went together perfectly and rifle works as good as any AR I own. Time will tell how long it holds up but initial quality for the price is better than expected. Thanks PSA for a great product at an exceptional value!!!

I'm very Impressed PSA! You have a A-1 operation going on!
First off I received my kit in 4 business days after submitting my order! Upon inspection after arrival I found the packaging to be exceptional in fact the full size padded rifle box it comes in is better than any of the top manufactures OEM rifle boxes that i have experience with. As for the product itself Blemishes if you even want to really call them that are so minor i really had to go over the upper hard to find them. Lower parts kit was bagged by component and perfect. The upper was machined assembled and test fired it comes very dirty gritty and oiled before putting this kit together it needs to be completely and thoroughly cleaned and lubricated! This is a critical part of preparing for a proper build! Building this kit went together with no error and fit and finish was excellent i used a Anderson stripped Lower. Taking it to the range i found the action to be smooth the accuracy is good with 75 grain ammo i had no problem zeroing in the sights. In conclusion I found the purchase of this kit the professionalism of PSA and the quality of my rifle to be way beyond my expectations. These people are definitely tuned into there customers needs and will do my Ar-15 related purchases here in the future!
