More directed at guido than anyone else, your scope knowledge is required.
Are all scopes parallax adjustable to airgun ranges? From what I have read on the net, some rifle scopes are parallaxed out to say 100m minimum (okay I'm thumb sucking that range), would they be adjustable to say 15m? Or does it depend purely on the brand and model of scope if there's enough adjustement.
Was looking at this site, more particularly this scope and the thought crossed my mind.
