Force on Force marker rounds boast superior performance, distinct marking and reliable ballistics. Designed to be shot at soft tissue for the ultimate realism, FoF rounds incur a pain penalty. Unlike other products on the market, these rounds are lead-free and thus safer for indoor use, environmentally friendly and prevent lead contamination and expensive cleanup. The marking agent never dries, making washing clothes and clean up effortless. Eliminating the use of powder as a propellant reduces the mess with significantly less barrel fouling.
