Zombie/ Survival.

This combo does not use a Wide Survivor or Wide Defence weight disk. Instead it uses the ring on the base, put it together to see what I mean.
AR: Turtle Survivor
WD: 10 Wide
SG: Left SG (Dranzer S Shaft Casings.)
Shaft: Bearing Base
BB: Magnet Flat.
This combo only works when using NSK bearings.
