CheyTac M200 is a bolt-action sniper rifle made by CheyTac USA LLC. It has a very big profile when it comes to size. This sniper rifle is capable of one-shot killing players and zombies. It can also disable vehicles quite easily. 

The major downside to this weapon is that it removes your backpack, which can make it quite difficult for snipers who value repositioning and mobility. It is recommended that you store the rifle in the backpack and only use the sniper rifle from a position where you can easily retrieve your backpack and are well-covered from flanking moves.
