RetroArms Hop-Up Nub Set – Type B

RetroArms Hop-Up Nub Set – Type B
The set contains two POM hop-up nubs designed for standard hop-up chambers. One nub has a convex shape and the other a concave shape, allowing you to experiment with different hop-up pressure settings. Thanks to their matching width with the pressure arms of hop-up chambers, the nubs are properly supported during use and do not deform. Both nubs are resistant to oils and greases.
Key Features

CNC-Machined POM
Both nubs are made of POM using precision CNC turning for accurate dimensions.

Convex and Concave Shapes
The set contains two nubs with different shapes, allowing you to try different hop-up pressure settings.

For Standard Hop-Up Chambers
The nubs are designed for standard hop-up chambers from various manufacturers.

Same Width as the Pressure Arm
The nubs have the same width as the pressure arms of hop-up chambers, preventing deformation during adjustment.

Resistant to Oils and Greases
Both nubs are resistant to oils and greases. During installation, a small amount of grease can be used to hold the nub in place.
