Gold…

Yeah I filed a groove in the brass deep enough to hold a tiny o-ring and wide enough for two of them. It worked very well for about 12 shots then they wore down and tore. I'm thinking 90d o-rings to for durability but considering the trouble I had stretching the standard rings over the bolt it would seem impossible with the 90d's.

I watching the rubber tube I put on the bolt (mentioned above) to see if/when it's going to tear and fall off. When/if it does I'll need to use something tougher like nylon beer line or something.
