Compensator not working?

I equipped a compensator to my trac 5-s. It is supposed to reduce vertical recoil.

Testing with and without the compensator showed no difference in the bullet patterns on the walls at all.

It is possible that the compensator is bugged for all guns, or that it is bugged for just the trac 5-s, but it's definitely true that it's not working on my gun at all.

Anyone else have any experience with this?

I couldn't find a bug forum

same here.... dosnt seem to work for any of my weapons.

message customer services... they'll tell you it's working fine, it just does **** all.
