Excellent build
With my stripped lower from Anderson, it was a breeze to put this together. When these go on sale I jump on 'em! This is a great way to build yourself a collection with out an enormous investment! I have customized these rifles just about every way possible... Lots of fun to mix and match..Everybody should have a dozen or two !! RH

It Says Blem, I Say Not
Just finished putting this one together, so any blemish would have been obvious...didn't see anything out of the ordinary. Also, thanks to PSA for including spare detentes, it's surprising how far they can go!

Excellent value!
Even though it's sold as a blemished model, I can't find a single blemish! Functions perfectly and is a hoot to shoot.
My father shooting this AR, first time shooting an AR since Vietnam.

Fantastic deal that made it affordable to finally get my AR15
Such a killer deal on this kit. Took about an hour to assemble, with the aid of a couple YouTube videos, for my first build.
Used an AeroPrecision stripped lower and had to throw this stupid featureless grip and stock locker to make it California legal....
Can’t wait to take it out this weekend and put some rounds through it!

Great product. Easy to put together with a Aero Precision lower, looks good, could hardly find the slight mark on the left side of the upper. Good thing its getting painted came. I will be buying some more. Keep up the good work.

Since I have put 100s of rounds thru it with no issues.
Thanks Pakmetto.

Good starter rifle ,truck rifle,beater
I assembled this kit on a LRB lower..Kit arrived fast.Packing was good.I inspected the kit & was unable to find any blemishes.Assembly of kit was without any issues.I had to make it kaliforniastan complaint with the addition of Strike industries fin,muzzle break & stock locked in place.So I can use standard magazines without legal issues.Yeah I know kaliforniastan sucks..I may buy another one of these kits.

Great Value
Great value - easy assembly into a $30 stripped lower and was throwing hot lead same afternoon with no issues at all! All components mil-spec and upgradable at any time one wishes. I've already added an inexpensive quad rail, flashlight and scope - and it shoots as well as anyone else's AR. Best part ... I've STILL not spent 1/2 of what they have! Great experience dealing with PSA!
