With our imagination, incredible engineers, and a desire to improve; we are constantly innovating an already amazing platform. We continue to explore how our innovative improvements can make you a faster and more accurate shooter. Innovation is at the core of who we are.

Military Grade


We torture test our rifles and pistols in the most extreme conditions, from the snow to the desert heat, they will function in any environment. The tight tolerances of the firearms protect the internal components from external elements. We Cerakote all our firearms to add to the durability. Multiple sources have reported that they have run our firearms in excess of the 50,000 rounds mark.

Match Grade


Our components are precisely engineered to the tightest tolerances. Our standards far exceed that of other manufacturers. We included match grade barrels and premium triggers in every firearm to enhance accuracy. Our Pro Buffer comes standard to reduce recoil allowing faster follow up shots. From the aggressive look and design to the quality of the components within, we are committed to assembling the finest firearms in the industry.



Every angle we cut, and every component we use, serves a function in our overall design that must be shot to be fully appreciated. At Cobalt Kinetics we source premium parts to compliment our high tolerances and precision engineering. Each component undergoes a strict quality control check before being installed into our firearms.
