TandemKross Challenger Bolt Knob - Ruger American Gen II

The TandemKross Challenger Bolt Knob is an aftermarket replacement bolt handle knob designed specifically for the Ruger American Gen II bolt-action rifle. The Challenger profile features an enlarged gripping surface compared to the factory knob, giving the shooter's thumb a more substantial contact area for smoother, more confident bolt cycling at the bench or in the field.

This dedicated Gen II upgrade from TandemKross is finished in black to match factory hardware. It installs directly onto the Ruger American Gen II bolt handle in place of the original knob and is sold as a single bolt knob component. The Challenger is built for the Gen II bolt assembly only - confirm your rifle generation before ordering, as this bolt knob is designed for the Gen II platform.
