Why choose this item?

  • Select the correct family: The GBB rubber is distinct from the AEG product, making version choice central to fit.
  • Match the complete assembly: Compare the chamber, barrel window and nub before adding the replacement rubber.

Design and use

The 4UANTUM Friction Pro GBB bucking is a hop-up rubber for a compatible gas-blowback airsoft barrel and chamber. Its shaped single-point contact patch is intended to provide controlled BB spin.
