Righty i want to order a new piston for my malossi 172 cylinder. I have a choice of 2 pistons the standard malossi one or the prox ones for the pm kits. But even there the prox have 2 sizes a A Grade (64.92mm) or B Grade (64.94mm) I did order a B Grade prox piston which ended up being the wrong size for the malossi kit, i could get the piston through the cylinder but it was extremely tight so i ended up selling it to a mate that needed it. What am i to do?
