    Yup. Parts kits have them. I just order spares each time I buy rebuild kits. I like to have spare banjo o rings around as well. As far as size spec. Idk. But don't use buna. They may fit. But the soft rubber is a pita to deal with.

    You can use buna orings if you want, but make sure they are a durometer of 90 and not the softer 70. A stiffer oring will help prevent barrel wobble when firing.
    Except for the Automag in front, its usually the man behind the equipment that counts.

    Any oring of durometer 90 in the correct size will work. I don't have my list in front of me, and I haven't used a twist lock for so long I can't remember the size off the top of my head. Size 018 sounds about right, though.
