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 Kevin Walther on Mar 13th 2024

    I did a lot of research to decide what to upgrade on my RPR yet to be received, but I really liked what I found with Anarchy Outdoors. I like the look and build of the product and am sure the design will be a great functional improvement. Aesthetically, it's beautiful!

  • Bolt Knob - Doesn't Stick Out Too Far

    Posted by BJ on Jan 11th 2024

    I like the shortened size of Little Bertha. It still allows good bolt control in all types of weather (with or without gloves) without protruding too far from the stock. It also allows slimmer gun cases to be used without removing the bolt or getting that (hard bulge trying to escape or destroy your gun case). Home Run on this one.

    One of the best upgrades for the Precision Rimfire...

  • Bolt Knob Upgrade

    Posted by Jeff on Oct 23rd 2023

    What a great upgrade. Not something I would have normally thought to do but the original one on my Ruger Precision Rimfire got severely damaged during shipping. Anarchy had the selection, quality and fast shipping I was looking for to get me back on the range.
