This bolt knob was designed by Area 419 to be the best all around bolt knob for competition and general use. Its main feature is the finger groove which allows you to manipulate the bolt with just your pointer finger without searching for the ideal position each time. Your finger automatically catches in the groove to assure the fastest, smoothest bolt manipulation. There are two knurled surfaces located on either side of the groove to give a sure grip.
- Made in the USA from 6061-T6 aluminum and anodized flat black.
- Defiance and Remington bolt knobs are threaded 5/16″-24.
- Remington knobs are 1-5/8″ long to accommodate shorter bolt handles
- Bergara and CZ 457 bolt knobs are threaded M6x1
- Mausingfield bolt knobs are internally threaded 10-32. Will only work on Mausingfield and Nucleus Bolts.

Bought this 419 Bolt Knob, that replaced my Bergara HMR knob, and I noticed a difference in how easier it is for my finger to grab onto the 419 knob and cycle the bolt. This is definitely a great mod and low cost as well. I highly recommend this!

Got the bolt knob for the CZ 457. I am more traditional and like the round bolt knobs better aesthetically, but after I used this thing, it will be a priority to put one on every bolt gun I can. Machining is spot and honestly, even the looks of it are growing on me.

This thing feels awesome on my CZ 457. Makes it feel like you’re running a full size bolt down.
