Had my TX venom laza'd ed back in the day.. They make a new piston with an alli body, to reduce the weight. This makes sense at mk1/2 strokes, but it too light for mk3 strokes. It also needs a stiff spring, so cocking effort gets firm.

Lightening was a good idea - but they went too far. Needs to come down to around 190-200g, not 160 or whatever it was.

On mine, the seal was venom with std AA fitment, not HW conversion, soas said above, that doesn't look venom. However, it is probably an improvement.
