Nice kit for the money.
This was my first AR build. Bought the kit from PSA online, then purchased a PSA lower from a local shop. My son and I got it all assembled and spent the 4th of July at the range. What a way to celebrate America's Independence! The gun performed very nicely. The polished trigger is great. An excellent kit for the price. I will be a repeat customer.

Fun rifle! Great shooter!
This was my first build. I put it on an Aero lower, and it has been flawless for over 1K rounds! Shoots well, especially considering I am a novice. Stock trigger was very mediocre, so I give it 4 stars.

Great budget AR-15
A lot of people recommended buying from someone else but I have been very happy with PSA. Processing took a bit but once it shipped it was here in less than 2 days. I built it with no prior experience the same day I received it. So far I have put 400 rounds through using a mix of .223 and 5.56 and I have had zero issues. I even threw some steel cased Tula ammo through it with no problems. However I wouldn’t recommend doing that on a regular basis.

I'm in love
10/10 would recommend. Parts fit perfectly into my Anderson lower. Easy to sight in and am having an absolute blast with this cheap build. Feels n shoots very nice. Exceeds expectations

Very good solid gun!
PSA provides above average ... towards top shelf components.
Fit and finish is very nice!
Color match to my Range Tool lower is perfect, fit was snug and not sloppy.
I'm not sure why anyone makes the m4 "grenade" barrel.... saves a little weight.
Solid performer!!!!
After 2k rds of M855 ... zero ftf or fte.
Accuracy is limited to me.... she was pulling 2-3 MOA at 100m.
I think some good glass and rest would half that.
PSA is rock solid, buy and shoot with confidence that this weapon will serve you well.

You get what you pay for i suppose.
The rifle upper looks great and the m-lok hand guard is top notch but there’s multiple scratches on the receiver and so far it fires but will not feed the next round. If i can get the feed issue sorted it might turn out useable.
