    I am in a niche market owning an Air Arms MPR precision 10m rifle with removable cylinder but general advice is sought from members.
    I refill every week just before competition so the cylinder gets unscrewed every week anyhow and so any argument about wear on threads is not so relevant.
    The question is, given the tendency for AA firing valve heads to extrude over time, is is better to have the cylinder out of the gun during the week and replaced just before use or leave it in all week and just remove for refill?
    For the sake of argument assume the cylinder seal is sound.

    To delay extrusion , my intuition would be to relieve the pressure .

    Air Arms just told me either way is fine but I agree with you Phil.

    I seem to be the only one publishing anything on MPR Precision and that is only stock mods. I have never seen one in bits.
