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

  • Big Bertha Bolt Knob

    This is the natural addition to Anarchy bolt levers. On my Ruger American 5.56 it is a perfect upgrade.

    I installed the Big Bertha Bolt Knob on the Savage 10/110 Threaded Bolt Handle Upgrade. As in my review of their Bolt Handle, Get One. You will not be sorry.

    Great product, feel and movement! I would highly recommend!

  • Best Bolt Knob

    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.
