- "Conversion kit to use lower caliber 5.45×39mm ammunition. Shorter range, faster fire rate, and less recoil to dominate close quarters engagements."
- — Description
It sacrifices range and punch for fire rate and stability, ideal for close-quarters combat.
- In the alpha, equipping 5.45×39mm magazines on the AK-47 would change the weapon name to AKS-74u. This feature was removed from the game on launch.
