Why 2 VOLUMISERS on the Force Fly?

[Solmyr]

I think I saw Rocky's Force, and it had 2 volumisers on it. And I read that the Force Fly come's with 2 volumisers. Where as the Angel Fly come's with 1 volumiser.
So are 2 better then 1 why?

[dynastySSS]

b\c they just want the gun to look a little better\ be a lil more ballanced. only the force fly come with 2.

The volumizer on the LPR side does not affect the performance of the gun. As dyanstysss stated the 2nd one is for looks.
