The large piston weight is there to compensate for the overloaded spring and tight seal.Originally Posted by Barryg
Does anyone know why AA fit that huge piston weight to new TX's ?
I have a fair few to choose from, I'm using a v-mach that is sized for a AA spring right now and I guess most of you use something similar.
Are any of you using something different?
Bin it, add a delrin top hat, size the seal and cut the spring to suit.
Mahoosive difference in shot cycle. Turns the "lazy" mk3 into a mk2 beater.
