Bo6 quickscope is hard?

I always been quickscoping in cod and im pretty good at it but something feels off when qs in bo6? I started with the sniper the first thing I did and my KD sucks right now 😅 Its hard to be aggressive with it and the sensitivity feels wierd. yeah i know I have to get it quicker with attachments but it takes forever when I get 10+ kills in a single match. Do you guys agree? Any tips?
