The MK35 ISR is a full-auto assault rifle added to Call of Duty: Black Ops 7 in the Season 3 update, and is also available in Warzone. It is described in-game as having low recoil for excellent accuracy while keeping a fast fire rate, which makes it easy to stay on target during sustained fire, giving it a versatile mid-to-long-range profile in both multiplayer and Warzone.

A low-recoil, fast-firing assault rifle built for controlled, sustained fire and accuracy at medium-to-long range.

How to unlock: Listed as a High-Value Target (HVT) reward on Page 3 of the Season 3 Battle Pass, available in the free tiers to all players regardless of premium purchase.
