The Cobalt Kinetics Cobalt CK-PRO-URG-556-75-B-FDE 7.5" CK PRO URG delivers a compact, premium AR-15 upper receiver group built around a 7.5-inch barrel chambered in 5.56x45mm NATO. Finished in a flat dark earth Cerakote with a matching free-float handguard, this upper is designed for shooters who want a short, controllable platform with refined fit and finish.

This upper is ideal for building a compact rifle or AR pistol dedicated to range use, training, or specialized roles where a shorter barrel is preferred. The free-float handguard and integrated top rail provide ample space for optics and accessories, while the precision-machined receiver and barrel assembly reflect Cobalt Kinetics’ focus on consistency and reliability.
