Achievement increase 100%

Hey guys.
As the title says I wanna talk about the VIP-Snipers.
I got the awm, and the barett equipped in bags. It says Achievements get boosted by 100%
Now my question is, is it the right way it works the way I think it does.

Lets say I kill someone, that kill obviously gets doubled and counts as 2 then. Do the 2 then aswell get doubled by the 2nd sniper rifle?
So 1 kill counts as 4 sniper kills right? Or am I trippin

Can you imagine this with the bonus daily mission cards we used to have where we could choose achievement increase
Dayum I would get my last badges quick then
