The U.S. Arms M4 UTAW Pro series rifle takes the already outstanding M4 UTAW and adds some gas to the fire. We always stand behind the principles that our rifles MUST be lightweight, durable, and accurate, and the M4 UTAW Pro series is no exception. This series is offered in 5.56 NATO or .300 Blackout chambering. This rifle can be configured with a black anodize or a multitude of Cerakote options for the handguard, trigger guard and receiver set. This rifle can be 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 claim we are “home of the World’s Tightest Receivers”. You may also spec this rifle with our standard lower receiver, but with fewer color options.
The M4 UTAW Pro series is available in multiple colors and finishes:
- Anodized Black
- Cerakote Black
- Cerakote Chocolate Brown
- Cerakote Gun Metal Gray
- Cerakote Alpine Dark Camo
- Cerakote Arctic Camo
- Cerakote Battle-Worn Bronze
- Cerakote Battle-Worn Titanium
- Cerakote Bazooka Green
- Cerakote Woodland Camo
U.S. Arms Company wanted to make upgrades to the already great shooting experience one gets from the M4 UTAW. This consequently and inherently made the M4 UTAW Pro series more accurate and gives the shooter more confidence at the range, on a hunt, in a competition, or for home defense. We made upgrades to the handgrip, trigger, safety selector, back plate, and give the shooter the ability to choose the type of lower receiver and muzzle device that best suits their needs. The barrel installed in this weapon system is constructed from a 4150 chrome moly cold hammer forging. The barrel is then phosphate coated, chrome lined, and equipped with a nickel boron barrel extension. As a result of using a nickel boron extension and the bolt carrier group being a U.S. Arms M16 full auto nickel boron bolt carrier group, allows the shooter to experience extremely smooth cycling. The Elftmann ELF-SE trigger in our base M4 UTAW was upgraded to the drop-in Elftmann Match adjustable trigger (2.75lbs-4.0lbs). This trigger is second to none in its class, with an extremely short take up, clean crisp break at a a 3.5lb pull, and a very short, positive reset which gives the shooter an overall better shooting experience. The M4 UTAW Pro series also comes equipped with an ambidextrous Radian Raptor charging Handle, a more ergonomic ERGO grip, and a Magpul QD back plate. More details can be found below.

These upgrades are subtle yet significant, allowing the shooter to have better shooting experience, more tools to be as accurate as possible, and of course confidence for home defense and sport shooting . The M4 UTAW Pro series rifle is the next level of perfection from U.S. Arms Company.
