Top end tuning kit for hw99

[airgun]

Are their any top end tuning kit for a hw99 i have a tinbum kit in it at the moment better than standard but still a lot of vibration its in .22 cal and running at 11.6ft\lbs but think it would run better at slightly low power what works for yous i know to a lot of people spending a lot on tuning a cheap gun is a waste of time but I seem to pick it up over my over tx200 and hw80 every time mad i know

The most expensive kit I reckon would be V mach, which I had in an HW99 and to be honest it made it quite harsh.
The standard spring along side your fitted guides should be pretty good, is there room for a piston liner, perhaps the spring is chattering inside the piston?

Send Nick (Tinbum) a pm on here - I'm sure you can send the rifle to him to have custom guides and parts made and fitted.

Pound for pound, it's probably the best tune out there at the moment.

I would think that if you have a TBT kit then you will have custom guides already as Nick only uses genuine HW springs if I remember right .

Thats if you got a full kit including a spring from TBT ?

Although a cheaper gun than the TX, the little pocket rocket '99 astounds many with its very refined manners and low recoil in a simpler and lighter break barrel format, and most definitely worth tweaking a little more to improve its manners further still.

As per the above, custom fitted guide & top hat and a piston sleeve are your friends here, combined with a responsible moly re-lube. If not already done, a de-burr and polishing of spring ends will most definitely help.
