Q:

Breech Removal for "0" Ring Change !

Can you remove the tank, lighten hammer spring, unscrew the cocking arm and remove the breech ? I really don’t want to unscrew the barrel as everything is very nicely in place.

Was planning on using 90 duro urethane O rings, as they are very wear resistant and good at higher (1500+) pressure according to McMaster-Carr.

I just remove the breech and dig it with paperclip. Im not sure what you are referring to with the duro 90… what i know is nbr90. They have shorter lifespan than the viton75 but they are tougher. Good for higher pressure. Smearing silicon grease on them helps with durability.

Well from what I have read on older post it can be done … I just bought “O” rings too …breech seals are 90 duro urethane. others are Buna-N 70 duro.
