Semi automatic UPPER

$1,225.00 – $1,575.00

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:

22 ARC , with an 18″ barrel, 1: twist and 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

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.

Our “Vitrum” drop in trigger is also included with every upper.

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, the 6 ARC with Factory Hornady 108gr ELD-M and 22 ARC with Factory Hornady 62gr/88gr ammunition.

100% American made with American materials.
