CTK Precision Universal Bolt Knob 5/16"-24 Thread Aluminum Black

The CTK Precision Universal Bolt Knob upgrade was designed to offer more leverage and easier bolt lift than a factory installed RPR bolt knob. Three ridges, machined onto the outside diameter of the body, allows for a positive grip on the knob while cycling the bolt. Because these ridges are machined, you'll never have to look for a missing O-ring, which could be the case with other bolt knobs. A CNC machined, hard anodized knob designed with functionality and installation ease in mind. The CTK RPR Universal Bolt Knob is equally at home on your Ruger Precision Rifle or your Remington 700. In fact, it will fit on any bolt with a 5/16"-24 threaded stud.
