We find red tracers cooler to use in night games as compared to the green glow in the dark ones to simulate a firefight in the dark. With that said, G&G Armament announce that they are releasing Red Tracer BBs which come in 2,400-round bottles. The recommended tracer unit to use are the G-01-036 (Black) or the the G-01-36-1 (Tan) which are also made by G&G.
