Federal law requires that you be 21 years of 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.

During our Cyber Monday Sale you can save BIG on this M4E1 Complete Lower which includes a 2-stage Nickel-Boron coated trigger, our NEW Enhanced Carbine Buffer Tube, and a Magpul MOE Grip.

The two stages of the trigger consist of an initial 2 pound pull that brings you to a "wall", where the hammer and trigger are set to break for the shot. After that, it’s only a 2.5 pound pull to fire, helping you make accurate shots with short resets in between.
