I poked around a bit and am finding it difficult to find what needs replaceing in a tm gearbox to get around 330. The spring yes, but does this require a new gearbox, gears, piston? And is it worth it?

all u need is a m100spring and bushings
there is no victory with out loss!!
What kinda of gun? A new TM m4 will be getting 370-380 with an m100. Slightly less on a 733 or g36. Maybe a stock CA spring or an sp90 will net you 330 or so.

an SP90 will put you at about 345ish new, but will settle down to around 325 after a few thousand rounds. As for bushings, my friend has been running a PDI 120 (about the same fps) with stock TM bushings for about a year and it has lasted at least 20,000 rounds so far.
the gun be a tm m16a2...so just some bushings and a spring thats it? It sounds so simple...and AEX would work on it right? (yes i know there is that hourly rate)
