Cobalt Pro Series Semi-Automatic Rifle 5.56X45mm NATO 13.7" Barrel (1)-30Rd Magazine Welded Green Finish



The Cobalt Kinetics Professional series is designed to meet and exceed the criteria for a practical rifle that can perform in the most austere (and unforgiving) environments while still being a refined tool. Critical factors taken into consideration during the design phase were; Accuracy, Operation, Recoil Mitigation, and Ambidextrous Adaptability. The end result is an elegant solution that shows what proper design and meticulous attention to detail can provide. Barrel lengths range from 7.5” to 16” to ensure that all mission specific configurations are accounted for and readily available to each end user.



We started by focusing our attention on the upper receiver group and redesigning our platforms to incorporate a better locking system for the barrel and hand guard. The result of our design efforts produced a reverse threaded barrel nut that seats the barrel evenly and provides more thread engagement than traditional externally threaded receiver extensions. The barrel extension seating surface is able to be machined to a tighter tolerance as a result of the reverse threaded system and allows the barrel to use 100% of its potential accuracy (that would normally be diminished by Mil-Spec receiver extensions that have high-spots). The free-floated hand guard is then affixed to the upper receiver via a 4 point (8 screw) mounting system that attaches right to the extended portion of the upper (which houses the new barrel nut). This creates a complete upper receiver system that will produce accurate results time after time. It also offers the best features of a mono-lithic upper receiver group without the drawbacks of the traditional examples found in the market.



The rifles are then expertly built by our trained gunsmithing team where one gunsmith focuses solely on one build at a time to ensure the production of an American Masterpiece. Every firearm goes through multiple inspections along the way to maintain the highest QC standards during the build process. Finally, all parts are inspected prior to being installed into the build. We have strived to carve out amazing OEM partnerships with the best parts/ accessories manufacturers (Radian, Geissele, B5 Systems, VLTOR, Proof Research, Rosco Mfg., etc) within our industry. The finished product is an exquisite example of what forward thinking engineering, superior parts selection, and a QC heavy production process can deliver.
