Why does this kit say it has a 2A Armament hand-guard included when other kits have the exact same hand-guard but just say a PSA hand-guard is included. In the pictures the hand-guards look the exact same but this listing claims this specific kit comes with a 2A armament hand-guard rather than just a standard PSA hand-guard. Is 2A Armament making hand-guards for PSA?

Can this kit be shipped to California ?
Brandon M on Apr 8, 2019
Does this come with every thing I need have a fully functioning rifle? Other than ammo and magazines do I need any other tools or parts?
Derek D on Feb 2, 2019
BEST ANSWER: It appears that you will need a stripped lower reciever to complete assembly
Is the bolt carrier parkerized outside and chrome lined inside?
Keith B on Apr 14, 2019
does the handguard have M-LOK at the 12o'clock position where there isn't rail?
Kaikai on Jul 11, 2019
BEST ANSWER: There’s a rail on top. Not m loc. It’s a standard picatinny rail. That’s what the pop up sights are mounted to in the picture.
Is this kit compatible with PSA AR-15 Lower Safe/Fire - 1728?
*Lew* on Apr 14, 2019
BEST ANSWER: Yep. I eventually swapped out the furniture for BCM stuff, but the kit itself made a excellent starter rifle.
Does the barrel have freedom 1/7 marked on it?
Chris on Jul 10, 2019
BEST ANSWER: Mine wasnt......it was marked "FN"
is the bolt black nitride?
Michael L on Jan 31, 2019
BEST ANSWER: It was black i cant remember if black nitride or not though

PSA 16" Mid-Length 5.56 NATO 1:7 Nitride 13.5" Lightweight M-Lok MOE EPT Rifle Kit With MBUS Sight Set, Gray - 5165450038
BEST ANSWER: The only difference between these two rifles are the hand guards, both are the same brand and same style with the exception of the Picatinny rail on top. It really comes down to preference ,the one that has missing Picatinny on top supposedly is lighter but you lose the ability to attach more items or accessories, versus the other that has Picatinny... both are excellent Rifle’s
Will the MBUS sight set be grey like the furniture with this rifle kit?
Hallie on Feb 3, 2019
BEST ANSWER: No, black.
The specs say that the overall length is 24.5 in. Does that mean this makes a short barreled rifle? or is that the length with the stock collapsed and the full length when extended is not an SBR?
William D on Dec 13, 2018
BEST ANSWER: No because it has a 16" barrel and most likely this is the shortest measurement when fully collapsed. Fully extended is what the Feds and most States go by.

As expected, no complaints.
What can I say? It was delivered quick and was exactly as advertised. Had only ever put together one AR before but it was easy to assemble. Everything operated perfectly and as expected. I love the upgraded trigger, a family member got the mil spec version and mine is noticeably and significantly better.

Nice upper for the price. I like the fact that they have so many build kits available. Will probably buy from them for future purchases.

Very happy with this purchase. Shoots straight and every time. What more can you ask for?
Would recommend to all. Very happy. Only bummer is that there is only rails on top. I should have done more research and gotten something with rails on the bottom as well
Works great, easy to assemble. Incredibly happy.
