I have recently bought an airsporter, there arent a lot of markings on it BSA, .22 and a serial number towards the left of the barrel GP04690. I guess it is a model S not quiet sure. it has an scope rail mounted on the cylinder.
I am thinking of re-blueing it and re-finishing the stock with a coat of matt PU clear. would like to increase the power output too..
could you please advise which model i own and the best possible mods that can be done to achive the best performance from this BSA.
How old is this airgun.
Does this model have a tappered piston if not can a gas ram be fitted.
