There will be a 30% restocking fee for all controlled items returned due to a failed background check or a denied underage purchase.

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.

The March inclusion of the 2023 Monthly Builder Set Program will make your friends and fellow range patrons green with envy. Coated by Blowndeadline, this set features a full gradience of shades between black and green that both break up the overall profile of the componentry and give it a look unique to other camouflage patterns that are commonly used. Whether you are building something for the field or something that you want to stand out from the rest-this builder set makes for a great start to your next build!

This builder set includes the finished pieces you need to assemble your own Basalt Overgrowth Cerakote M5 (.308) Rifle.

This finish is available one time only and in limited quantities, so get it while you can!
