What is blemish?
Doug S on Apr 23, 2018
BEST ANSWER: Small imperfection some people would not accept when paying full price. Mine was a very small scratch that would occur with use anyway and would have no effect on function.
What is a typical defect in a blem kit?
944turbo944 9 on Apr 23, 2018
BEST ANSWER: More times than not, it is usually just a slight discoloration in one part. Functionally, it is the exact same as a non-blem.
Is this the whole kit !anythng else I need?
Robert B on Apr 26, 2018
BEST ANSWER: You will need a lower receiver and a rear sight or optic.
does this kit include all the parts of a "lower parts" kit and all that is needed is a stripped lower?
keith s on Apr 23, 2018
BEST ANSWER: Yes, will need a back sight or optic of some sort
Any special permits to purchase this kit?
Al M on Apr 23, 2018
BEST ANSWER: Probrably depends on your state and local laws, In North Carolina, there is no permits needed for this, the only part that needs paperwork is the lower reciever on this type of gun.
Can you recommend a stripped lower for this product?
Rex S on Apr 26, 2018
BEST ANSWER: I got two of these and put one on a DPMS and one on an Anderson. Anderson seemed to fit just a tad bit better but really any mil-spec stripped lower should work.
Does this kit have everything besides a stripped lower?
Woby118 on Apr 26, 2018
BEST ANSWER: yes - exception being a rear sight.
Is the front sight fixed so it can’t be removed ?
Joey J on Apr 24, 2018
BEST ANSWER: it is a "Fixed Sight" but it can be removed - but you will need a decent punch and hammer to remove it. You can also get a punch block that is molded for the barrel and sight post but if you dont want to spend the money like me I use a roll of duct tape under the barrel and knock the pins out that way. Dont recommend doing it unless you already have a good set of tools to start with and are good with tinkering with things - if you put a gas black on and dont have the gas port lined up it wont cycle right.
Im not trying to bash, or advertise any other companies; from a monetary and simplicity perspective, will a popular companys mill spec. Polymer lower receiver work with this upper ?
Brian R on Apr 26, 2018
BEST ANSWER: Yes, in fact I have a polymer lower on this kit. It works great.
Do you have a diagram of how all the parts go together of the gun?

All your kits are high quality and easy to assemble. (Even easier with the upper already assembled). And the price can’t be matched anywhere that I have found

Finally, put it together, and wow all my friends were impressed, took them shooting to sight it in, had one hell of a sighting in party.

50/50 chance on these
Bought two of these build kits. Both units look nice however something is off with one of the uppers. Put a fixed rear sight on the rear and had to adjusted windage full left. Tried another sight but still had the same issue.

Totally good to go!!!
Another “blem” built on a dirt cheap budget. Runs 100% and shoots where I aim it.

Good deal for the money
Bought it only because the price was so low...did not expect much, but I was really surprised. It looks nice (still don't know why it's considered a blem). Added an anderson lower and handle/rear sight...ended up around 380.00 gun. Haven't shot it yet. Nice, low priced AR.

I built it for my grandson, he and his father want to shoot informal 2 gun shoot (rifle and pistol) at a local range. It was an excellent kit, like all of the other PSA products that I own it worked well from the start. It is a BLEM but like all of the BLEM products that I own, it’s usually really hard to find the blem. No problem in recommending it to any one

Looks good.
I haven't fired it yet. I built it and took the lower receiver in for engraving.
