Built to look like the standard U-100 to avoid suspicion from the management, the inner-workings of this weapon were completely overhauled for precision accuracy and enhanced power over distance.
The U-ARX Dirac is an "auraxium" variant of the U-100 Lastly, sharing much of the same design. However, the Dirac places a much higher emphasis on the ranged power of its parent weapon—integrating a 3.4x scope into the pistol, greatly boosting the weapon's projectile velocity, and increasing minimum damage from 125 per shot to 143. These perks come at a sacrifice to both magazine size and reload speed, however.
A compensator redirects gases upward, reducing vertical recoil by 30%, and increasing hipfire cone of fire by 15%. The added sound pressure causes the player to show on the minimap 35m farther away.
The weapon's muzzle flash and noise generation is reduced, and the player no longer appears on the minimap when firing. In exchange, the weapon's damage falls off 20 meters sooner and bullet velocity is reduced by 15%.
The rail mounted Darklight Flashlight can illuminate hostile cloaked infiltrators and dark areas but the light can give away your position. The light can be turned on and off with Toggle Attachment hotkey.
It is possible to earn both Ribbons and Medals while using the U-ARX Dirac. Each ribbon is a standard reward for achieving a set amount of kills with the sidearm. Medals are awarded upon reaching kill milestones with the weapon.
