Cobalt Kinetics KeyMo Muzzle Device Features The Cobalt Kinetics KeyMo Muzzle Device is machined from steel and finished in a durable black nitride coating that resists corrosion and wear from repeated firing cycles. Threaded 1/2x28 to fit standard 5.56x45mm NATO rifle barrels the device measures 2.75 and weighs just 6.2 oz adding minimal bulk to the muzzle end. Cobalt Kinetics engineers this device with precision both internally and externally so it works smoothly whether run alone or beneath an attached suppressor. That dual purpose design gives shooters flexibility without needing a separate device for each configuration. Running a muzzle device like the KeyMo helps manage recoil and muzzle rise allowing for faster more controlled follow up shots during rapid strings of fire. Because the device is purpose built to complement a suppressor shooters planning to add one later can expect smooth consistent performance without needing to swap hardware. The compact 2.75 length keeps the rifle s overall balance close to a standard configuration.
