All you need is a Crosman 13XX / 22XX transfer port seal.... It fits perfectly, conforms to the curvature of the valve and breech, and seals great.... plus the ID is a lot larger than stock.... HOWEVER, it may put your QB over 500 fps and then you will need a PAL.... It will depend on how restricted the porting is in the flow through bolt, but you would definitely need a Chrony to make sure....

No not regular oring. Looks like a piece of black tubing cut about a 1/16'' or 3/32'' in length.

You can get them from www.scopesandammo.com .... EMAIL Eric and tell him what you want.... but be advised he has a minimum order or charges extra.... They look like an O-ring but with a square cross-section and are about 0.070" thick....

I ordered the seal kit from Archer Airguns and had no problem getting it into Canada. There are some items they won't ship to Canada but the seal kit isn't one of them. Although, due to the shipping costs, it's probably only worth buying from Archer if you are ordering other items as well. I also got their muzzle brake and hammer debounce kit.
