How to adjust the hop up on tippmann hpa

[SmithyyyUK]

Hi Guys,

Ive recently bought the tippmann hpa cqb v2

Im having difficulty adjusting the set screw on the hop up? its not an allen key as its just a circle hole?

Also it does have a TDC installed but i have no idea how to adjust that either? can someone help

I had the older version tippman a good few years back that used the orignal hop adjustment (hole on the side with allen key sized adjustment.

I then used a tdc mod that was also an allen key adjustment. Removing the original one.

I'm thikning the newer models must be along the same lines?  tdc adjustment via an allen key from the top? I think i remember the sizes being US though and not metric? so be careful not to strip the adjuster.

Adjust clockwise/anti clockwise for more or less hop.
