Gradous Bolt Knob

The Gradous bolt knob was designed by Robert Gradous and was designed specifically for our bolt handles or any Defiance machine bolt handle.  It's very similar in design to our bolt knob but it sticks out slightly further to give mover leverage on your bolt handle.  We offer two different options to our customer's based one their personal style of shooting.  We feel our design allows you to run the bolt faster but the Gradous knob follows you to have more leverage.
