The FPS Hop-Up Nub HU60N V2 (60 Shore) is a replacement part for V2-style hop-up units. With a measured hardness of 60 Shore, this nub promotes dimensional stability and wear resistance compared with softer inserts, supporting consistent BB positioning during feeding.

Suitable for routine maintenance, overhauls and tuning of AEG platforms, replacing a worn nub helps maintain consistent flight performance and feeding reliability. Installation requires basic hop-up unit disassembly; professional fitting is recommended for complex interventions.

Concrete benefits: V2-specific spare with calibrated hardness for durability and BB stability, simple replacement and straightforward integration into maintenance routines.
