Federal law requires that you be 21 years or age or older to purchase a stripped receiver or frame. If a frame or receiver can only be made into a long gun (rifle or shotgun), it is still a frame or receiver not a handgun or long gun. However, they still are "firearms" by definition, and subject to the same GCA limitations as any other firearms. See Section 921(a)(3)(b). 18 U.S.C. Section 922(b)(1) makes it unlawful for a licensee to sell any firearm other than a shotgun or rifle to any person under the age of 21.

Outstanding Product with a Couple of Nit Noys Review by Joseph
There were some minor hiccups along the way, but nothing serious enough to downgrade a five-star rating.
Lower Receiver:
A little better QC would have avoided the first issue. When assembling the pivot pin, the spring would only go into the recess about 1/2 inch. A quick chat with Jonathan revealed that he suspected residue left from when the hole was drilled. He suggested placing a drill bit in the recess and twirling it between my thumb and finger to remove the debris. That worked like a charm.

The spring and detent for the take down pin are held in place by 4 40 x 1/8 set screw -- but the set screw is not included with the receiver or in the lower receiver parts kit.It's not really an enhancement if the needed set screw is not included. I proceeded without it and used the end plate to hold down the spring as is normally done. But again -- what's the point of the enhancement?
Finally, I really liked the hex head roll pin for the bolt catch release and the integrated trigger guard.
Upper Receiver:
So easy to install the barrel and the gas tube. I loved it.
Hand Guard: More set screws (8), but installation is a breeze and the design results in a really strong bond with the upper receiver.

I am a newbie, but this combo build kit is clearly a winner. I recommend it highly to anyone thinking about using it in a build. (Posted on 3/5/2018)
