    Airsporter/ mecury piston

    Hi,

    looking far a piston to fit a Bsa Airsporter S, I believe the mecury piston is the same? Is there any difference between the standard piston and the S models?

    Cheers

    As far as I know the pistons are the same but I admit that the question made me look at the Chambers diagram. They list the piston parts with the same code number.
    And for reference: the piston O ring is BS212 but it can sometimes help to fit the O ring from a Meteor BS210 if the BS212 is very tight.
    Cheers, Phil
