AR Rifle Kits

Kits available in 5.56 NATO, .223 Wylde, 6.5 Creedmoor, .308 Winchester, and 300 Blackout.

Join the club of amateur gunsmiths and dedicated shooters who've proudly pieced together their own AR-type rifles from scratch. Each of our Rifle Kits features mil-spec fittings and coatings, and every component is precisely forged, hammered, CNC machined, and coated stateside. Our kits run the gamut, from retro A2-style shooters to subsonic 300 BLK guns, to precision bench rifles in 6.5 Creedmoor made for confident 1,000-yard shots.

Are AR build kits legal?

Yes. Federal law and the Bureau of Alcohol, Tobacco, and Firearms do not recognize any components in these Rifle Build Kits as a firearm. The Gun Control Act of 1968 allows for a private individual to build a firearm at home, from scratch, with no serial number or paperwork required. Keep in mind, this pertains to federal law. Some states have enacted restrictions against Rifle Kits like these, or otherwise recognize such kits to be firearms, contrary to federal law. Be sure to check your local and state laws before purchasing. We cannot fulfill orders to some states. We strongly recommend reviewing our Shipping & Returns policy to ensure your state is not restricted before ordering.
