Are you guys just buying the O-ring kit from Airsoftparts.ca? Or, do you have an online source for bulk purchase of those O-rings (and, favour, could you provide links for the exact ones required, 'nades are the Madbull multipurpose and the high-power 204's).
Have you ever tried silicone grease instead of oil? Something with enough viscocity to actually 'stay' there?
