I'm basically asking if a standard gun can be "optismised" for performance: range/accuracy with the parts it has fitted, such as adjustments or lubing etc, or would this type of basic "optimising" require parts to be added, like gearbox shims?... different hop rubber etc.
I don't know if there is anything wrong per se, just wanted to try and make it as good as it can be without it being modified, maybe addressing any weak points of the out-of-the-box set-up, a bit like servicing a car I suppose.
To make sure it's tip-top without spending out too much. I don't mind taking it to a tech if it's worthwhile, but if the work wouldn't be too complicated I may try myself!
Does that make more sense?
Cheers
