Little Bertha Bolt Knob by Anarchy Outdoors

The Little Bertha Bolt Knob, similar to the Big Bertha bolt knob, has an hourglass shape. The design of this bolt knob makes it more comfortable for individuals with regular or small hands. The diamond-shaped rivets enhanced the grip.

It comes in a matte black, red, or polished titanium. Each option provides a sleek look, making it an excellent addition to your gun.

This smaller knob has two thread sizes; the standard 5/16x24 and the M6x1. The 5/16x24 works with all custom-made Anarchy handles. The M6x1 fits the CZ 457 and other similar model handles.

The Little Bertha is 0.803 inches in diameter and 1.495 inches in length. The anodized aluminum versions of these knobs weigh 0.8 oz.

  • Little Bertha bolt knob

    Posted by Jon on Aug 24th 2023

    This knob is excellent. Just the right size, I didn’t want one that was humongous. Nicely rounded and helps me cycle the bolt so much better. Well made and nicely finished. Highly recommended.

  • AA Little Bertha Bolt Knob

    I've tried allot of bolt knobs over the years and keep coming back to this particular model. ( I have one on a custom CZ457, Bergara B14r and now a Vudoo 360.) It adds some length (and leverage) to most bolts but isn't silly big. that , coupled with the design of the finger slot and moderate texture is "Goldilocks " right regardless whether I'm slow rolling off a bench or speed shooting from position. Fit and finish is above most brands . The titanium finish match's nice with stainless barrels as well.

  • Love it is everything I expected.
