how often should you change the O-rings on 162EI

[jjjjj]

according to the Morini162EI manual you should change the O-rings every 2-3 years, is this required? does it have to be this often?

thanks

it depends on how often you shoot and whether or not you keep a charged air cylinder on it all the time. serious shooters probably need it every year. sometimes they will last 6 years plus if seldom used and if you keep the air cylinders of them.

Thank you for the last reply. Here is couple other questions, how do I know When I should change the O-ring, is there any indications like rapid drop in pressure or inconsistent shots … also can Pilkguns change the O-rings, if so about how much is it and is it a difficult task to do?

Thanks

How many O-rings are there that needs to be replaced regularly on 162EI, where are those O-rings at and is it a do it your self project or does it require professional smith’s attention.
