The Simunition 5.56mm Conversion Kit is a drop in conversion intended for use with the AR15/M4/M16 and C7/C8 rifle series.

The safe use of Simunition® 5.56 mm reduced energy Cartridges in the M16/M4 and C7/C8 weapons requires the installation of a Simunition conversion bolt & bolt carrier assembly. Proper installation of the bolt/bolt carrier assembly is required to help preclude the inadvertent chambering and firing of live, lethal operational ammunition and ensure the proper operation and cycling of the weapon.

For safety reasons, Simunition® conversion bolt & bolt carrier assemblies are manufactured from the same quality materials as the original service components they replace, but are visually different to help distinguish them from operational bolt & bolt carrier assemblies.


NOTE: Intended only for supervised training conducted in accordance with Simunition® safety training protocols by Law Enforcement, Military and Simunition® approved Commercial Range Programs.

    I bought 2 sets. Came with bolt carrier assembly, cleaning cable, and brushes. Oiled them up, put them in 2 uppers and went to work. Function as new! If I had more of a need I'd order more for sure.
