HI Everyone
Trying to get back into airguns after a 15year break
I've still got my bsa mercury and would like to overhaul it
ie--new spring ,seals ect
I have an exploded parts diagram of the gun but know idea how to strip it down and remove the main spring ect
I have managed to remove the stock but thats all
anyone have any info on how to do this or are there any manuals available
or is best to let an expert do it

The BSA Mercury's quite easy. After removing the stock, the trigger block simply unscrews from the rest of the cylinder, counter clockwise I think (it can be very tight). Be cautious as the thread nears it's end because the spring can pop out quite violently if there's a lot of preload on it.
cheers for that
will give it a go

As I said though, be very careful when you're unscrewing the trigger block. A good (safer) idea might be to put it in a sash clamp after you've opened it to a certain point, (I've used a block of wood with a bit hollowed out of it to take that thin protruding bit of the trigger block), then turn the action to unscrew it rather than the trigger, easing off the sash clamp as needed.
