There's been a discussion about this before
Dont know if this would be good business sense but maybe marker manufacturers could just design a new main body for there particular marker and it would just a case of removing the old and fitting the new sized main body....anyone got pics to compare the size difference of the 2 balls (haha) ?
could current loaders accept them ?
barrels i would imagine not but then again inserts (like the freak inserts) could be introduced. Same goes for the breech i suppose, each company makes a .5 breech sleeve for any pre 2011 markers say and from then on they make them .5
