what is the handguard length on this kit 6 or 12"?

Goes Bang! Every Time!
Not interested in a 'Luxury' AR, just want it to go bang every time I pull the trigger. PSA does that better than anyone!

Great budget shooter
Put lower together, added a sling and a Primary Arms Advance Micro and now I have a great shooter without breaking the bank. Rifle has about 300 rounds fired in it, no failures of any kind. Rifle sighted in for 50/200 yard zero and has no problems hitting what I aim for. 6" gongs at 100 yards, no issue.

This is now my truck gun, and I would (have) bought other rifles from PSA.

Packed flawlessly, assembled it with a Bushmaster lower and everything fit perfectly. Have not tried it yet but expect no problems. Waiting to assemble 2 PSA pistols, 10.5 and 7.5.

Palmetto State Armory does have any quality control at all.
First Ar-15 build!! I'm new that's clear but as we all know this is not a hard gun to build. I learned how to build this with friends in AROTC. Now that it's done and all the issues fixed it's awesome! But wow PSA had to take the whole upper back 2 times for being out of spec. Then I found the BCG was defective and was damaging my buffer face (very badly) so needed replacement also. PSA takes about 2+ weeks to process returns, so if you have anything defective, it's going to be a while before you get anything back. Overall I do not recommend PSA I had way to many defective and out of spec parts, I plan to build a new rifle again soon and will not be using Palmetto state armory. But again now that my rifle is using very few Palmetto parts it's kick ass.
Titanium CarboNitride bolt carrier is what I went with and it is great!

Front takedown pin too big
I have purchased from psa a few times and I will say their prices can’t be beat for what you get. But this time the product was not up to par, the front takedown pin was to big and would not fit, after going to my local store for a new takedown pin all was good. But otherwise the fit and finish was very nice. I’m sure psa would have sent out a new one but for $3 I took care of it myself.

Very good kit!
I decided to give this rifle kit a shot several months ago when it was on sale. The upper paired good with an Anderson lower. My teen son has produced nice consistent groups at 25 and 50 yards using A2 front and mbus rear sights. It helps to have young eyes. We have had zero stoppages. Pmags work perfectly. The enhanced polished trigger group is an improvement over standard mil spec. Not a match trigger but worth the extra dollars. Parts come in seperate plastic bags for each sub-assembly. This is helpful for a first time builder. PSA packs a couple extra take down springs a detents that often launch across the room never to be found. The bolt carrier group is comparable quality to some that cost more. The finishes are nice. I cannot find fault in this value packed kit.

Very pleasantly surprised!!!
Very happy with this buy!!! Rifle quality is very good and it is ACCURATE! I unboxed it, put a USGI A3 sight/handle on it, mounted the upper on my other lower and went directly to the range and shot 32 straight Xs on a B-27 at 50 yards using 24.5 TAC and a 55 Hornady FMJ -- prone, off the mat, with a sling. Perfect function, no FTFs or jams. Point of impact didn't shift as it heated, either. Barrel quality looks excellent. The Magpul furniture is nice, quality stuff. The only reason I'm giving it 4 stars instead of 5 is that the buffer tube and charge handle appear to be 6061, not 7075 aluminum, and I can't comment on the trigger yet because I tested it with a different lower. Those are minor issues, though. That being said, this deal cannot be beat. Great stash/SHTF gun for the money. I absolutely would recommend buying it. THANKS, PSA!
