So my question is have any of you replaced a firefly spring, or have a suggestion of which spring to use that would be more powerful than stock, yet wouldn't damage the plunger tube?
Stock spring dimensions:
11/16" OD
3.5" Original Length
Note: I've searched the forums and Google and have found nothing related to a firefly spring replacement that won't damage the plunger tube, the firefly doesn't have much feedback.
