Blue Jean Operator features the RECCE LMG made by Red Right Hand LLC. Red Right Hand designed a unique LMG upper inspired by the COLT LMG, built for sustained fire. It uses a heavy HBAR barrel for durability and a new Heat Mitigation System (HMS) to manage heat. The HMS uses aluminum heat sinks to draw heat away from the barrel and a copper coil to cool the gas tube, both extending the lifespan of the upper and improving operator safety.
