The Grav is one of the two new primary weapons in Call Of Duty Season 6: Black Ops and Warzone. And being a solid, full-featured assault rifle, it's already proving more popular than the Rawhide .410 rifle, which is better suited to specialized builds.

The best gear for the Grav will depend on your play style and personal preferences and how you are using it, but for solid, multipurpose gear, we recommend the following attachments:
Muzzle - Agency Suppressor
This increases recoil control, which is always important for any fully automatic weapon, and makes you much less noticeable, which is especially important in Warzone's various battle royale modes. You also lose a certain range of effective damage and bullet speed as well, but it's worth it.
Barile – 21.3 Task Force
This long barrel amply offsets the penalties to effective damage range and bullet speed imposed by the agency's suppressor. It will increase your recoil a bit, but the other attachments in this loadout will compensate for that.
Optics - 3x Axial Arms
This is simply the best lens for long range shooting, and is actually quite useful for more accurate medium and short range shooting as well.
Underbarrel – Grip Field Agent
Combined with the agency suppressor, this grip will compensate for the increased recoil caused by the Task Force barrel. Overall, you'll end up with very low recoil and tight grouping. The grip slows down the speed of the shooting movement a bit, but this has little impact on most styles of play.
Magazine - 50 Rnd
In general, you will want to use the largest magazine, so as to increase your chances of killing your enemy before you need to reload (and he takes the opportunity to kill you).
