Semi Automatic Complete


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

A 6061 Billet aluminum upper and lower, a match grade 416R stainless steel barrel from Preferred Barrels and a Mil-spec bolt carrier group are at the heart of the rifle.

We offer the semi auto in:

22 ARC, with an 18″ barrel, 1:7 twist and a Rifle +1 gas system

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

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

A 15” MLok handguard ensures you have enough real estate for optics, designators, bipods, tac lights, blenders, chainsaws, bayonets and whatever other peripherals you want. Our UP “Vitrum” single stage, 3lbs trigger gives you a crisp, clean break and short reset while the Magpul MOE K+ grip and MOE SL stock provide a familiar, reliable, and ergonomic feel. You can also choose the PRS Lite stock for more adjustability.

Just as with our Bolt Action ARs, we offer a manufacturer’s warranty and a Sub-MOA accuracy guarantee.
We accuracy test our 223 Wylde with Hornady Frontier 75 gr. BTHP factory ammunition, the 6 ARC with factory Hornady 108gr ELD-M ammunition and the 22 ARC with factory Hornady 62gr/88gr ammunition.

1- Magazine (30 round, where legal, with the 223, 10 round with the 6mm ARC and 22 ARC)
