Can this kit be shipped to cali?
Franco on Nov 8, 2018
BEST ANSWER: If you have to ask, the answer is No
I just assembled this kit and very happy. But has no castle nut. Is it not necessary?
Harrison F on Nov 15, 2018
BEST ANSWER: It is not necessary for this setup but when I installed a KAK Shockwave brace I had to get a castle nut.
Is the lower receiver included?
Elliot A on Nov 4, 2018
What do I need to finish the build?
Neil W on Nov 11, 2018
BEST ANSWER: Looks like a just stripped lower and maybe some sites or optic
does this include the bolt carrier group and charging handle?
vary a on Nov 3, 2018
BEST ANSWER: Yes, see the description about the bolt.
Does this require an ffl to buy this?
Neil W on Nov 10, 2018
BEST ANSWER: No FFL for uppers. The lowers are considered the gun by ATF and will need to be transfered by an FFL.
Is this handguard proprietary? Or can it be replaced with an aftermarket one?
Mel S on Nov 14, 2018
BEST ANSWER: You can replace it with whatever AR-15 compatible hand guard you choose.
What hand stop is compatible with this?
Eric C on Nov 13, 2018
BEST ANSWER: Any M-Lok hand stop as long as it is not too long in length should work.
Can a complete pistol kit M4 5.56 without the lower be shipped to California?
Franco on Nov 7, 2018
BEST ANSWER: Check with California laws. I believe it can be since you don’t have to have a FFL to have it shipped directly to you.
Does the upper come assembled?
A Dizz on Nov 8, 2018
BEST ANSWER: Yes, the upper, bolt carrier group,barrel shroud & charging handle all assembled. The lower pieces, come in little bags separated for easy assembly/ identification.Whole shebang only needs a stripped lower to go.
Will this accept any sort of brace or blade?
Jamee C on Nov 5, 2018
BEST ANSWER: Typically a brace or blade requires a special buffer tube. A kak blade may fit but it would not be ideal seeing as the buffer tube is smooth and the blade would not be able to be tightened down properly (kak blades should be used with kak tubes, they have dimples for tightening the blade down).
Can this kit be shipped to North Carolina without a FFL?
Ronnie W on Nov 14, 2018
BEST ANSWER: Yes. It is not a gun.
is the buffer tube mil spec or commercial size ?

Perfect truck gun, combined with a brace.
This build kit came fast, the upper was already barreled! Psa shipped in less than a week. A great buy without a problem after 1200 rounds of federal, Tula, it eats everything.
