This entry details the KAK Industry Water-Cooled AR-15 system showcased at Shot Show 2026. The design integrates the barrel, gas block, and gas tube within a water jacket, inspired by historical 1917 cooling methods. This system is engineered to maintain component temperatures below 212°F, theoretically allowing for indefinite firing as long as water is replenished. The system can operate in belt-fed or semi-auto modes.
