Learn how to change the hop-up nub on your Silverback VKS.

The VKS is supplied with three hop-up nubs:

Low (0 µm) – factory installed
Medium (+250 µm)
High (+500 µm)

If maximum hop-up adjustment is not sufficient to lift your BBs, install a taller nub. If the hop-up tends to jam too easily, a lower nub may provide better reliability.
