RS2 Piston

Is there anyway to modify the piston to use apex seals instead of the seals with the screw hole in the middle ?

I haven't seen one firsthand but if it's like several shooters I've done you may need to machine a piston button that excepts the screw and upgraded piston seal. Hopefully some of the family here will jump in with some more helpful info for you. Ed

If so, maybe Compasseco has replacement piston seals.  (A Macarri seal would be nice, tho...)

BTW, I bought a seal button from http://www.airgunsmith.com last year - it was for a B3, very reasonably priced ($6 I think).  Buying from his website is confusing, however.  Does anyone else machine buttons for general use like this?

Yes you can machine a button like Ed said to adapt for a JM seal.But you must make sure that you keep the same overall length with piston and seal attached. Very critical or you will either lose FPS or bottom the piston out.
