Uintah Precision who’s known for their precision BOLT-ACTION AR-15 pattern upper receivers has recently announced their new precision SEMI-AUTO AR-15 pattern rifles.

Uintah Precision states “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 16” match grade 416R stainless steel barrel from Preferred Barrels, and a Mil-spec bolt carrier group are at the heart of the rifle.

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.

The single stage 3.5lbs 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.

Just as with our Bolt Action ARs, we offer a manufacturer’s warranty and an MOA accuracy guarantee. 100% American made with American materials.”
