Systema Complete Mechboxes
Somebody help me out here. There are two models listed:
GB16V25R-12-0 M16A2, SR16-M4 M120 Spur Gear Set / Torque Up Teflon Cylinder Set
AND
GB16R-12-0 M16A1, M16VN M120 Spur Gear Set / Torque Up Teflon Cylinder Set
What's the difference? The A2 and A1, as well as the SR16 and the VN are all rear-wired....I don't get it. Anyone help me here?
