My pistol makes a popping sound at the breech that is annoying to me and probably my neighbors. Could I be missing an o ring ? There is not one there that I can see so maybe I need to install one ? Any help will be appreciated.
I believe my Brocock Contour is basically the same action and has an o-ring in the breech. My bet would be that the breech o-ring seal is missing and needs replaced. Brocock is not good at telling customers the size of the o-rings. My gun is a .22 cal and a .177 might be a different size. Hopefully someone will know the size and chime in. It might be helpful to know if it is a .177 or .22.
