Isn't there somebody who has found an American equivilent oring that can be substituted for the S1K breech seal? They've been out of stock for weeks. Same with Diana Breech seals. I found that a #110 oring works excellently for my Diana 350Ms. In the plumbing world it's known as a #8.  Its spec is OD=9/16 x ID=3/8 x w=3/32.

Surely there's a substitute that will work for the S1K...somebody?  Anybody?   :o

Maybe shave some height off of the original seal and then put a #203 on top of it?

#203  od=.574  x id=.296 x .139    or    9/16 x 5/16 x 1/8

Dunno if it's still available, though. Didn't see it on his website.
