Silicone M-nub designed for use with R-Hop and Flat-Hop setups etc..
The silicone elastic rubber is the optimum nub material used alongside R-hop builds, as it applies an evenly distributed pressure to the hop rubber to ensure the force on the BB is as consistent as can be for a stable acceleration before exiting the barrel. This will help with the accuracy and consistency of the shots. The M-nub is elastic doesn't deform outwards contacting the inside of the hop unit.
Provides consistent pressure to the R-Hop patch, increasing accuracy. Simple to install.
Each pack contains 2 M-nubs, each approximately 3x3mm thick with a 3M adhesive back that is to be stuck on the modified hop-up arm.
