Big Bertha Bolt Knob by Anarchy Outdoors

If you have large hands, the Big Bertha is the bolt knob for you. This bolt knob allows our hulk shooters to grasp their bolt handle and move it with ease. 

The hourglass shape of this bolt knob increases dexterity for the shooter, and the diamond-shaped rivets increase grip. Those that like this design, but prefer a smaller bolt handle, should check out our Little Bertha Bolt Knob

We offer this bolt knob in matte black, red and polished titanium. Any of which would make a great addition to your rig. All you need to do is attach it to one of our many aftermarket bolt handles

    Bought a new rifle so straight back to Anarchy Outdoors for another Bertha Bolt Knob. Big Bertha this time and just as ergonomic and good looking as the Little Bertha. The side of your finger just naturally drops into that groove and the bolt throws better than any original factory knob.

    I have the Dragon scale and the Big Bertha. I like the groove on the Big Bertha. Seems to fit ideal to my thumb for one handed cycling and brass capture.
