Recently I’ve been playing quite a lot of CODM. I have nearly reached level 150 which is the maximum you can get to. My favourite gun is the M13 or the Koshka. It’s a very good
sniper rifle with fast ads and 
deals a lot of damage. It’s my favourite gun because of the
fast ads and the light weight
magazines. I will make a video about it soon. It’s been released quite a long ago but still it’s the best sniper in my opinion.
