Replacing the O-Rings on your gun can make a huge difference in performance. If you are having some tech problems with your gun you probably have some bad O-Rings. Leaking air, the bolt not re-cocking, and low FPS are all signs that it's time to replace your O-Rings. The Maddog Designz Master O-Ring Kit has O-Rings for every gun, and even your tanks.
