Is the buffer tube 7075 or 6061?
Thomas N on Sep 15, 2018
BEST ANSWER: asked PSA customer service the same thing, was told they manufacture their own tubes and yes, 7075
What all do I need to finish the kit?
Eagle on Sep 10, 2018
BEST ANSWER: A lower... and you might want a magazine too.
the MOE handguards... are these the current MLOK series or older original MOEs?
orion on Sep 11, 2018
BEST ANSWER: when i received mine its the new mlock style even has label on it
I know the bolt is carpenter 158 but is the BCG HPT,MPT properly staked grade 8 screw shot peened,gas key hardened to USGI specs,is it 8620 steel M16 profile carrier chrome lined phosphate coated?
Crystal W on Mar 17, 2019
BEST ANSWER: Mine was marked MPT and appears to be in proper order. I'm trying to figure out what coating they used. It's pretty slick.
What is the difference this Barrel and the freedom series Barrel?
Michael W on Sep 14, 2018
BEST ANSWER: it IS the freedom barrels. The freedom barrels are nitride (or phosphate) the premium ones are cold hammer forged and chrome lined. This is nitride, thus it's the freedom upper. the only differences between the two lines are the barrel. The Premium ones use chrome lined barrels from FN, while these use another brand (no one know what it is) that is nitrided
what firing group does this kit have ?
Sam E on Sep 12, 2018
BEST ANSWER: If you mean 'what fire control group,' as noted in the description, it's their EPT trigger, which is a milspec FCG with PSA's EPT trigger/hammer. You can search their site for more information on that but it's definitely a step up in quality and makes this an especially good deal.
Do you need to go through an FFL to purchase?
Mark A on Mar 14, 2019
BEST ANSWER: No, you do not need to go through an FFL for this rifle kit because it does not have the lower receiver. The receiver is the serialized part that needs to have an official transfer through an FFL.
Does this kit come with the lower?
Gary K on Mar 14, 2019
BEST ANSWER: Nope. You order this AND one lower receiver if you're looking to build a complete rifle. The upper and the lower parts kit will ship to your house. The lower will ship to your FFL. Happy building.
Is this chambered for 556 and 223?
Zack O on Feb 20, 2019
BEST ANSWER: Yes, you can safely shoot either in this rifle.
What kind of BCG coating is on the bolt in this kit? Just got mine and it's super slick. I dig it.
John T on Mar 25, 2019
BEST ANSWER: I'm pretty sure the whole gun and parts are nitride coated, including the BCG.
Can you mount a scope without the iron site getting in the view of the scope?
Zachattack on Mar 24, 2019
BEST ANSWER: Enter an answer to this question.You can if it is raised up to look over the iron sites. I have one with a vortex strike fire red dot on it. It has no magnification on it, but you can see the iron sites through the red dot. I would not use this gun to put a scope on.
What special tools are needed?
Zack O on Feb 22, 2019
BEST ANSWER: There are really no special tools needed. Because the barrel is already together that eliminates the need for a castle nut wrench. I did find the easiest way to assemble the magazine release is with a fuller gauge. This is small enough to slide behind the release in order to hold the spring. If you have never put one together I advised going on YouTube there several step by step videos there. Good luck. Oh have a good vise to hold the lower while your putting it togeter.
So is this a complete upper? Does it include everything?
Fab808 on Mar 20, 2019
BEST ANSWER: Yes includes everything, buy a lower and assemble then go shooting
would I have to replace the handguard to have the ability for grips?
Chevyman365 on Sep 20, 2018
BEST ANSWER: You mean like a vertical or angled foregrip? If that's what you're asking, then no. You can attach MLOK accessories (including foregrips) directly to the bottom of the MOE handguard.
Can you ship this rifle kit to California?
Craig N on Sep 10, 2018
BEST ANSWER: It is a complete upper and parts to complete a lower you must purchase elsewhere. Have fun building it, YouTube has some good assembly videos.
Is this an HBAR, making it MD legal?
Han S on Mar 19, 2019
BEST ANSWER: This has an M4 barrel which is (medium), HBAR is Heavy Barrel. This is not HBAR.
Does it come with carry handle?
Daniel A on Mar 15, 2019
Was this kit supposed to come with a sling attachment for the stock?
steve s on Apr 4, 2019
What's the difference between this & SKU#516444983?
Aaron B on Mar 25, 2019
Can this kit be shipped to home address?
Mike L on Mar 19, 2019
BEST ANSWER: Yes, it is legally just gun parts since there is no lower receiver which is what is clasified as a gun and has the serial number.
Does this item require FFL to ship?
Charles T on Mar 16, 2019
BEST ANSWER: No it does not. It does not contain the lower receiver.
Is it in compliance with New York State? can I shoot it left-handed?
Joseph W on Mar 14, 2019
Will this accept a bayonet? If so how?
john111 on Mar 14, 2019
Can I get this same deal in black ?
Raymond D on Mar 13, 2019
What is the ETA on these being back in stock?
Chris on Oct 29, 2018
Is this PTAC or Freedom line? there's no descriptor saying "Freedom" like they usually are, and just wanted to make sure that the PTAC was just these "unlabeled" kits nowadays

Amazing value. Will buy another!
Fantastic rifle kit, paired it with a No Step on Snek lower. Lightweight, accurate, zero malfunctions after 400 rounds.

Sorry but I only have 90 rounds down range to zero my sights and scope that I found. So far it's on target on the Iron sights and scope OUT OF BOX. I need to move both 4 right and 1 down. And I built it with basic tools in the kitchen drawer. Check with me later this week I have ammo to BEAT DA HELL out of it. My total build is $425.00 lower/kit/sling/scope/vertical grip.

Very nice quality and shoots well.
Everything but the bolt catch pin was easy enough to assemble. Not PSA's fault at all, but during the install I lost the bolt catch pin and ordered a roll pin set from some place on Amazon.

Outstanding Kit !
This was my first kit from PSA. I have since ordered 4 more kits since March of this year ! The fit, finish and function has been outstanding on every kit I have ordered from PSA ! I am buying 1 kit per month on average now, just built the 10.5 kit for 279.00, and it is a beast ! I fully endorse PSA kits as do several friends and family members now ! This is my kit from last week, delivered in 6 days !
She's a beast, like every other kit I have built from PSA !
