set for the creation of 2.5 and 3 mm Hop-up Nubs

Rubber beads with diameters of 2.5 and 3 mm are used to produce pressure rollers for hop-up chambers. Dimensions of the pressure roller vary among different manufacturers. If a too narrow roller is used in the groove of the hop-up chamber, it can result in uneven pressure on the hop-up rubber, leading to imprecise shooting. These rubber beads can be cut to create rollers tailored to the width of chambers from various manufacturers.
Each manufacturer has a different range of hop-up mechanism adjustments, and with a specific diameter, the hop-up effect may be either too weak or too strong. That's why the package includes two different diameters – 2.5 and 3 mm rubber beads made of NBR 70sh for their production.
