KWA Maintenance

[snuff]

My KWA is approx' a year old,it's well maintained but is there anything I should do as an anual service type thing.
There are no issues,it fires as good as it's always done......(not tempting fate)...

Is leave it all alone but well cleaned. If anything is on its last legs, it'll probably break when you open it, which will be bad as kwa parts are hard to get hold of
