The hardest-working part in your hop unit
The hop-up rubber, or bucking, seals air behind the BB and applies the backspin that lets it fly further and flatter. The nub sits above it and presses the rubber onto the BB as you dial in your hop. This SHS set gives you both parts together.
Consistent power and range
The rubber is made from a durable compound that holds its shape and resists tearing. Fitted correctly it tightens up your air seal for steadier power and gives you cleaner, more repeatable backspin for better range and accuracy.
Fitment
It is designed to fit Tokyo Marui spec hop-up units, which covers the majority of standard airsoft AEGs. If your gun uses a non-standard chamber, please check compatibility first, and remember that a fresh bucking and nub work best alongside a clean, correctly seated inner barrel and hop arm.
