Ok my homie has Showtime cylinders and the o rings are shit, so I order a rebuild pack from prohopper but they the regular ones cuz they don't look that big. So we put on the o rings but we had the hardset time gettin em on. So I took the old one and compared it to the new ones and there is significant size difference. My question is, will the rings from prohopper fit for showtime? and if so, did i get the wrong size?
