Robert G on Dec 7, 2018
BEST ANSWER: It will ship, this upper is completely legal in all the other non communist states. It's up to the comrade to please the state.
What lower do you recommend?
Darren T on Dec 6, 2018
BEST ANSWER: I would say PSA first, for a PSA kit, but just about every mil-spec type lower will work just fine.

Jhonas V on Jan 1, 2019
Do they come with a sight?
Leslie S on Dec 8, 2018
BEST ANSWER: Roy D sure puts the D in his name!!
Where does the third spring and detent go that came with the takedown pins?
DurtayMcGurtay on Dec 15, 2018
BEST ANSWER: The third spring and detent goes in the lower... because the FIRST one has usually gone sailing across the room.

is this a complete to make a complete rifle? If so does this have to ship to an FFL?
David on Dec 11, 2018
BEST ANSWER: I read the description, I didn't see where there was a lower included in the kit.. so you would need a lower receiver. No lower = no FFL needed.
will it shoot .50 cal. BMG ?
not-applicable on Mar 30, 2019

Just saying in the description it states what caliber it is fore.
Is the muzzle break pin and welded?
Jeremy G on Dec 10, 2018

Evan A on Feb 9, 2019

Is the charging handle included with this? I don't see one in the pic.
Jarhead on Dec 20, 2018
BEST ANSWER: Gordon K is right. the description says 'yes.' And I just checked the pic and there's clearly a charging handle shown right there.
The picture shows lower components, but some of these questions say that you have to buy another one. Is the picture wrong?
Tman1267 on Dec 24, 2018
BEST ANSWER: You need a stripped lower receiver. The kit includes the parts to complete your lower receiver and the rest of the rifle

Dk44689 on Apr 7, 2019
Is a striped lower all I need to finish this kit?
Frank F on Apr 29, 2019
BEST ANSWER: this IS the parts kit. This and the stripped lower (and a 6 pack to help you focus) and you're good.
Is the rail a picatinny?
Dk44689 on Apr 6, 2019
BEST ANSWER: It's a m-lok free float rail with about a 2" or so picatinny rail on the back and front of the top of the rail for your preferred sights or optics. If you want to add anything on the sides or bottom you will have to add picatinny rail attachments.
Is this a full kit? If not what's missing?
Cody B on Mar 1, 2019
BEST ANSWER: The lower receiver and sights ....add those 2 items to this kit and you get a solid,surprisingly accurate rifle at a great price.
does this include a magazine? someone on youtube said it did.
bingball on May 8, 2019
BEST ANSWER: No mag is included. However, PSA is always running deals on ammo and mag combos.
Does the MBUS front flip-up work with this handguard or does it need modification like it does with Aero handguards?
Mark S on Apr 28, 2019
BEST ANSWER: I don't use the Magpul sight specifically, but I have an el cheapo knock off for the time being and it fits fine. Granted I had to slide it on rather than pop it on because the sight doesn't stretch any after loosening it up, but it has not given me any problems. Assuming the MBUS is as close to the knock off as it should be, it should fit just fine.
Wen will this deal end?
Jeff L on Dec 13, 2018
BEST ANSWER: When PSA decides to end it.
Can a foregrip be attached to this with without any modifications? Couldn’t tell from the picture but it looks like it can not.
Raymond S on Feb 20, 2019
BEST ANSWER: Any M-lock compatible grip can be attached directly to the handguard, or any rail compatible grip to a section of M-lock rail. The only interference may be the gas block.
It says it includes a lower kit is that correct?
H O on Dec 27, 2018
BEST ANSWER: Yes, it says it includes a lower build kit. You are CORRECT. YAY!!! Is there anything else in the description that it says it comes with that you want to ask if it comes with?

tits magee on Dec 15, 2018
Is the grip sealed?or will I need a plug for the bottom
Rootin tootin on Dec 21, 2018
BEST ANSWER: What do yo mean, "...need a plug for the bottom?" Why would you need a plug for the bottom of the grip? You don't need a plug for the bottom of the grip.

Lance S on Dec 17, 2018

For the price it's an amazing rifle. The stock and pistol grip are A bit on the cheap side but for a starting AR it's an amazing deal!
