Rubber round bars in 2.5 mm and 3 mm diameter for making precise pressure rollers for hop-up chambers. The dimensions of the pressure roller vary for different manufacturers. If a too narrow roller is used, the hop-up can be unevenly pressed on and cause loss of precision of the gun. From these blanks, you can cut custom length rollers that fit hop-up chambers of various manufacturers.

Additionally, every manufacturer's hop-up is different in the way it behaves in response to the pressure applied by the roller. You may find that with one diameter, the hop-up effect can be too weak or too strong. The package contains two different diameters – 2.5 mm and 3 mm – to best fit your gun's needs.
