Is there any benefit to have Metal Rotation ring with ball bearing for the tanks?

What does it do?
TIA!

Beware that the openings on these metal ones are different than the plastic ones so depended on your set-up in the turret, you might need to cut openings which is not pleasant.nexusys wrote:Thanks all for the answers.
I already have 360 mod done.
So, this means it will smooth out the rotation of the turret. I might consider getting one.
