The U.S. Arms Company M4 UTAW Champion Series is the most advanced weapon system we offer. We took the key design elements from our M4 UTAW Champion Rifle and fit it in a package that automatically creates smiles among gun owners.
The M4 UTAW Champion Pistol is a semi-automatic AR-style pistol chambered in .223 Wylde so it accepts, chambers, and fires both .223 Remington and 5.56 NATO flawlessly. This weapon system makes for one of the best AR pistols on the market and is equipped exclusively out of high-quality components, from the upper parts to the lower assembly. It is lightweight, accurate, and durable. We stand behind our name on every rifle and weapon system we manufacture. The Champion Series is the main platform used to showcase our bleeding edge technology and what we are capable of at U.S. Arms Company. This weapon system is offered in .223 Wylde or .300 Blackout chambering.
The M4 UTAW Champion Series AR Pistol can be configured with several Cerakote options for the handguard, trigger guard and receiver set. This AR Pistol comes specced with our patented Cam Lock lower receiver so that you get the tightest receiver fit on the market. The Cam Lock lower receiver will also fit any mil-spec upper assembly. We are proud to be “Home of the World’s Tightest Receivers”.
This pistol is available in multiple colors and finishes:
- Cerakote Black
- Cerakote Chocolate Brown
- Cerakote Woodland Camo
- Cerakote Arctic Camo
The barrel installed in this weapon system is derived from a cold hammer forged 416R stainless match grade blank. At 8″ in length, this shorter barrel is great for a compact feel and small enough so it’s always secured in the right place of your home or vehicle. The barrel is turned, glass bead blasted, and equipped with a nickel boron barrel extension. As a result of using a nickel boron extension and a U.S. Arms nickel boron bolt carrier group, the shooter experiences extremely smooth cycling. To aid in the best shooting experience, the M4 UTAW Champion AR Pistol also comes standard with a state of the art gas system consisting of an SLR .750” adjustable titanium gas block along with an SLR pistol length Melonite gas tube. This allows the shooter to adjust gas flow according to the type of ammunition and suppressor combination being used. This pistol is suppressor ready straight out of the box or violin case. We are proud to run Elftmann Tactical triggers in this weapon systems. Our M4 UTAW Pro Series Rifle comes equipped with a trigger second to none in its class; the Elftmann Match Trigger, which is easily adjustable from 4lbs to 2 3/4lbs without removing the trigger from the lower parts. As a result of this performance, it only made sense to have this trigger in our M4 UTAW Champion AR Pistol. This gives the shooter a custom, crisp and clean trigger break every time the weapon system is fired. Other additions to this series are Magpul MBUS Pro steel iron sights, a Maxim Defense CQB Gen 6 Pistol Brace with an H1 buffer assembly, an ambidextrous Radian Raptor charging handle, and a Strike Industries Venom flash hider. This weapon system is then packaged in a discreet violin AR pistol case from Peak Cases.
The U.S. Arms M4 UTAW Champion Series is meant to set you apart from the crowd in looks and performance, whether it is a Champion Rifle or Champion AR Pistol. The M4 UTAW Champion Series is the highest level of excellence from U.S. Arms Company, making it one of the best AR pistols available today. We took everything good about our M4 UTAW Champion Rifle and put it an AR Pistol package that can fit under the seat of a car, next to a nightstand, or in the closest camouflaged in a violin AR pistol case. This weapon system provides a signature look and design aesthetic that’s unlike any other in the market, while giving the shooter highest level of confidence and flawless performance in competitions, sport shooting, and defense for years to come.
