Nope, it won't - the stroke they are at is the minimum to make the power, with any spring, such that adding preload / meatier spring reduces power, not increases it. They are right on the limit (in terms of spring power for the given stroke)..
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
