I know there are several barrel orings in the classic parts kits, and i think in the rt parts kits.

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.

Thanks for the help!

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.

so just to be sure I am looking at Buna 90 018 size is this correct?

[athomas]

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.
