MadBull 60 Degree Shark Hop-Up Bucking x2 + Fishbone Spacer x2 airgun rifle precision metal gear setsWhy 60 Degrees? 60 degree rubber is softer than normal 80 90 degree rubber. Much easier to install and operate than the softer rubber bucking. The B. B. will shoot out easier and without headaches and need less skills to upgrade. Cons: This item may last shorter than the regular rubber. How to install: Please apply some oil outside the bucking when installing. Also, remember to replace the spacer to the X type one. NOTE: X spacer is not good for all
