Just after some advice for my gun. Can the standard gear box cope with a slight stronger spring? If so what can I put in to get closer to the 350fps mark? Currently running 300/310fps only upgrades so far is a madbull tight bore.
Yup, but lose the Madbull (they are more a replacement barrel than an upgrade and are no better than OE for quality) and pop in a Prometheus 6.03 or PDI 6.05
The gearbox will be fine up to around 400fps with no real extra wear.
