If you want silence;

TM motor that's comm lathed by someone that knows what they're doing
Helical gears that are shimmed PERFECTLY, Debatable on the mixture of bushing/bearing I find bushings on the bevel, sector and bearings on the spur gear to be the quietest
Sorbothane pad on your cylinder head, and a MASK white POM piston head w/ sobo tablet
MOSFET with active breaking / Soft start to kill even more motor nice
Silencer that's god a very good composition of foam inside it...

I'm just trying to figure out if that mechbox would actually silence or change the pitch (you're still sucking a fair amount of air for the piston... where would that air 'come' from for the sealed mechbox).

Please tell me more about the lathed motor... I haven't heard that one before.

There are some other tricks that I know of (but most of them are small returns on the silence factor, mainly done for other reasons):
Polishing the interal mechbox rails for a smoother ride
Bearing spring guide for not torquing the piston
heavy weight oil between the inner and outer barrels.
some sort of ear plug or similar instead of the hopup spring, so they hopup is consistently against the mechbox
If mechbox/body allows, good UMWPE tape between the mechbox and body to dampen the transfer of mechbox noise to the metal body. (This is similar to foaming a sniper rifle)

Any other little tricks?
