Just picked my my new no me mercury S. A mk1 i believe? Square stock in blonde walnut.
It has a barrel from a standard mercury in .177 flavour fitted.

It shoots nicely but i will strip and re-build it anyway.
Apart from the usual clean up, internal polish and maybe guides, top hat and liner etc is there any other tricks i should consider while its apart?

It will be a dedicated 25-30 yard garden pigeon gun.

Also, will all merc stocks interchange?
It sits next to my MK1 airsporter and i cant help but compare the stocks and think the merc would look much nicer in a mk1 airsporter style stock. I have the skills to modify a merc stock but dont want to hack up the S stock so was thinking of maybe getting a standard merc stock to play with.

Must say, im very impressed with it. No idea what power its putting out, but a dozen shots or so in the garden, freezing cold and a bit gusty results in ragged single hole groups at 20-25 yards. Better than i ever managed to achieve with my hw77, crossman 2260, mk1 airsporter or webley mkIII.
