We manufacture our Semi-Auto upper to include the same design elements and high-quality standards that our Bolt Action uppers have. Top tier, USA-made materials and components combine to make an AR for all scenarios; from hunting and competition to self-defense.

Our uppers feature a 6061 Billet aluminum receiver, a match grade 416R stainless steel barrel from Preferred Barrels, and a Mil-spec bolt carrier group.

We offer them in:

223 Wylde, with a 16" barrel, 1:8 twist and Mid-length gas system

or

6mm ARC, with an 18" barrel, 1:7.5 twist barrel and Rifle +1 gas system.

Rounding out our semi-auto upper is an ambidextrous charging handle and a 15” MLok handguard that ensures you have enough real estate for optics, designators, bipods, tac lights, or whatever other peripherals you want.

Just as with our Bolt Action ARs, we offer a manufacturer’s warranty and a Sub-MOA accuracy guarantee. We accuracy test the .223 Wylde with factory Hornady Frontier 75 gr. BTHP ammunition and the 6 ARC with Factory Hornady 108gr ELD-M.

100% American made with American materials.
