The Simunition® conversion kit, conversion bolt, bolt carrier assembly, and safety-ring insert allow the FX® Marking Cartridges and the SecuriBlank® to be fired safely from the user’s own service weapon. These easy-to-install kits help preclude the inadvertent chambering of live ammunition and ensure the proper operation and cycling of the weapons. They are an integral part of the FX® training system along with the FX® marking cartridges and the FX® protective equipment.

Simunition® believes that realism is the most important aspect of effective law enforcement and military training. Based on the concept of realistic training, Simunition® has developed conversion kits that allow users to train safely with their own service weapons and duty equipment in single-shot, burst or full-automatic mode. These innovative and high-quality kits produce realistic recoil and ensure the proper operation and cycling of converted weapons with FX® and SecuriBlank® training ammunition.

Most Simunition® conversion kits are easy to install and require no special tools. Simple, yet reliable and safe, these kits require replacement of the duty barrel on most pistols and the upper receiver or bolt for rifles, carbines, and machine guns, installation of safety rings in revolvers, and a safety adapter in shotguns. Weapons can be quickly converted back to operational status once training is over. The kits are made from the same type of high-strength materials as duty weapons and are designed with various safety features to help preclude the chambering and firing of lethal, live ammunition.
