Tandemkross Challenger Bolt Knob for Ruger Precision Rimfire Rifles and others

• Textured and extended for easy use
• Customizable with removable O-rings
• Durable and lightweight upgrade

Operating the bolt in your Ruger Precision® Rifle has never felt better thanks to the Challenger Bolt Knob. Featuring an enlarged profile, multi-faceted design, and removable o-rings for customizability, the Challenger is made to fit common 5/16"x24 thread pitch bolt handles. While the bolt knob can easily be hand tightened, it also features a socket for a 5/16" allen key to mount it to the bolt handle securely. An included polymer cosmetic cap may also be optionally used to keep out moisture or debris.
