You can only unlock these kits once your weapons reaches its maximum level. Here are all the Conversion Kits in MW3:

  • JAK Heretic Carbine Kit (MTZ-762 Battle Rifle): Transforms the MTZ into a close-quarters carbine with enhanced mobility.
  • JAK Raven Kit (MCW Assault Rifle): Converts the MCW into a high-powered DMR with increased range and accuracy.
