Aftermarket replacement complete male fill valve for the Webley En4cer / Enforcer air rifle.
Common source of leaking this spare replaces the complete unit on the rifle and is already assembled.

Complete unit with internals already installed.

Converts it to a standard Forster fitting – an improvement on the original filling adaptor (which will not work with this). If you do not already have one of these they can be purchased here,  we also stock a suitable dust plug cover here.
