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.

This Navy Builder Set features an M4E1 set with a Navy Cerakote finish by Nevada Cerakote.

Inspired by the Carriers, Cruisers and Destroyers of the United States Navy, these battleship grey sets feature Navy Blue anchor insignias on the left side of the receiver and handguards. This insignia is also hard laser engraved on the receiver's magwell; a special touch from the folks at Nevada Cerakote.

This package deal includes the finished pieces you need to assemble your own Navy Cerakote M4E1 Rifle, including an M4E1 Enhanced Upper Receiver, AR15 Gen 2 Lower Receiver, 12" Enhanced M-LOK Handguard and Billet Trigger Guard all finished in custom Navy Cerakote. Stand out at the range with a unique and eye catching build. This is a one time offer for this finish - once they are gone, they are gone!
