Why 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 AEGs.
• If you have problems shooting, please apply some oil "inside" the bucking.
