What special tools if any do I need to assemble this ?
Steve T on Sep 25, 2018
BEST ANSWER: A set of roll pin punches, a big plastic bag, and a small hammer are all you really need. Use the plastic bag to catch the pivot pin detent and spring when they go flying. A pivot pin installation tool, and a set of bolt release installation pin punches makes the job go quicker

BEST ANSWER: The flash hider is NOT pinned.
I notice this comes with the PSA Enhanced Polished Trigger (EPT) FCG. Is that the same as the PSA single stage trigger?
john d on Oct 24, 2018
BEST ANSWER: If by "PSA single stage trigger" you mean their "mil-spec trigger", then no, EPT is single stage also but much smoother, I have both and EPT is much nicer.
Is this rifle mil spec?
Rhys P on Nov 13, 2018
Since the barreled upper cones assembled, I woukd expect the headspacing was verified at assembly by the PSA factory. True? Or do I need to verify before attaching the upper once I build out my lower receiver?

Flawless appearance
I have seen and own firearms from many manufacturers both low cost and take out a second on the house expensive. This PSA upper exceeds the quality of uppers at 3-5 times the cost. If it shoots as good as it looks it will be a superb shooter and the biggest bargain in my safe. Demonstrative of US built quality firearms. Kudos to all the manufacturing and assembly team folks. Why pay more?

A great deal, grab one!
I put mine together on an Anderson Mfg. lower. Everything went together with no problems. The EPT trigger is three cuts above the typical GI-style that comes with the standard kits. Throw in the MBUS sight set and this is a real bargain. The stock and grip color is a very dark grey, almost black, which is fine by me. I added a Magpul oil bottle that stores in the grip, and the included front sight adjustment tool fits in there fine too. All in all, this is a great deal, you should get one. Or two. Or maybe three.

Amazing shipping and fit
Just came in today. Ordered it on a Friday and it was here by Wednesday. I have to say everything fit well and the extra spring and detent pin came in handy. I’m gonna take it to the range this weekend and see how she handles. Will update if something happens but I’m sure it will be fine

Best deal you will ever find, and a great rifle to boot.
By far the best budget kit, likely that there has ever been. I’ve seen this barrel get sub .5 inch groups at 100 yards. Will not fail, unless you shoot a ton of steel cased ammo and allow your chamber shoulder area to build up carbon. The rail is quite awesome, I wasn’t in love with PSAs first few lines of rails, but they’ve got it down now.

For anyone on the fence, this is the best deal you will probably ever see. If you add up the bonus parts on top of the base kit, you’re getting one hell of a deal, roughly $150, which is twice the standard cheapest kit price for a rifle you can trust. (Also PSA deal)

Fit like a glove
This is my first build with Palmetto State Armory. All parts fit together nicely. Great build. Great price. I have already ordered another kit. Thanks PSA.

Very Satisfied
Quality Mil-Spec parts with Magpul furniture. You can not buy an AR for this price let alone the quality.

This kit is awesome. Shipping was fast and discreet, the shipping label just says PSA (no logos on outer box). I paired this kit with Aero Precision lower, Strike Industries simple featureless grip, stock stop, Tacfire ambi safety and
Aim Surplus A2 muzzle break (CA stupid laws). I've ran mostly American Eagle and Fiocchi 55 gr. .223 rem with zero hiccups. A rifle with this feature set would cost you more than $800 in CA, I paid $450 not including tax or dros. Thank you PSA.

Excellent value, zero issues.
Ordered and had it at my door in a few days. All parts were there and went together easily. The Magpul MOE stock is a touch "loose" but nothing terrible. I ran 500 rounds of Wolf steel case through it in two days, not one malfunction at all with nice groups for cheap ammo.

After buying a lower you get a very nice AR for $399 or less.
