    Default Mendoza RM-2003 main piston seal

    Hi.
    Newby needs some help sourcing a main piston seal for a Mendoza model RM 2003 SA Advanced. I picked up the rifle at a bargain price basically for my son to practice in the yard, and for the occasional PC of those pesky flying things that come from India. In all a solidly made weapon that has proved to be consistently accurate even in the 15-20m range.
    I have searched all over the net and cannot seem to find one anywhere. The seals shown on some suppliers' sites are definitely not the same as what it looks like.
    Does anybody have an idea where I could source one or what alternative is there available, I've considered possibly getting one machined but what would I machine it out of?
    Any help will be much appreciated.
    Thanks Okes.

    You can use nylon or Teflon.

    Polyurethane is the right material if you want to make your own.. Difficult to machine. I have tried. My speeds and feeds were to slow..

    Post a pic of the seal. Or maybe the piston can be modded to take somthing a bit more readily available.
