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 Features:

  • Diameter: 0.945 inches
  • Length: 1.753 inches
  • The design allows for easy handling
  • Included rivets allow for better grip
  • Thread Pitch 5/16x24
  • Compatible with all custom Anarchy Outdoors handle products. 
  • Made in the USA

*All of our standard thread knobs will fit on the Christensen Arms Standard Rifles

    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.

    I installed this with the Anarchy Outdoors bolt handle on my Bergara B14R build and what a difference. It’s adjusted right above my finger it does not take much to start lifting so it definitely speeds unloading and loading up quite a bit, plus it looks sweet!!
