The SRC Bucking Rubber is a replacement hop‑up bucking designed for use in AEG (Automatic Electric Gun) airsoft rifles. This essential hop‑up component ensures consistent BB backspin, helping improve accuracy and range when your original bucking wears out or if you’re refreshing worn internals.
 
Key Features
Durable Rubber Construction: Made from quality rubber to provide a reliable seal and consistent performance throughout play.

BB Weight Compatibility: Suitable for use with standard airsoft BBs in the 0.20 g to 0.30 g range, giving good performance across typical skirmish setups.
Improved Consistency: Helps restore smooth, reliable BB backspin and trajectory when installed in an AEG hop‑up unit.
