The JAK Beholder Rifle Kit is a conversion kit for the TYR handgun featured in Call of Duty: Modern Warfare III as part of the Aftermarket Parts system. It was added as part of the Season One update.
It effectively turns the TYR into a Marksman Rifle, improving damage ranges and recoil control while harming mobility, however, losing the ability to wall hang.
