    • Tackleberry from USA asked:

      What size is this port considered? I want to get a dust cap for a Discovery, and I am assuming this is the same size.

        This does work in the Discovery, it is the same as the factory fitting that comes in the gun.

      Will this fit/work on the Benjamin Woods Walker (3000psi)?
