Top hat choices for a TX and that huge factory piston weight

[averageplinker]

I seem to recall reading that that big heavy top hat was a factory fit to get the power in.177 up to comparable levels with .22"
As with all received wisdom this should be treated with caution.

Yes thats correct. The weights are the factory way to manage power
A well set up TX does better without these weights in any calibre.
