From DownSights: “The latest addition to the plethora of Marksman Rifles in Warzone is the new SP-R 208, which is also known as the “R700.” The SP-R 208 marksman rifle was added into the game in Season 6 and can be acquired for free by reaching the Battle Pass tier 15. This new rifle might be under the category of Marksman Rifle, but it holds a heavy-hitting power that far exceeds the existing sniper rifles in the game. This rifle can easily replace the Kar98k meta”
