Area 419 (5/16″-24) Bolt Knob

(14 reviews) Write a Review


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.

  • 419 bolt knob, black

    Posted by Adam on Feb 10th 2024

    The bolt knob is top notch quality and finish. Price is fantastic when compared to others that cost twice as much and are inferior quality. Only issue I had was that the base was slightly smaller than the titanium handle on my Tikka T3. The edge is sharp actually, but a small black washer mated them together nicely. Good job anarchy outdoors

  • Area 419 rocks!

    First bolt knob change was to a Catalyst Arms Hammerhead - works great but looks kind of clunky. Second try was the Area 419 and it's awesome - the groove guides the index finger into place like the Hammerhead, but a much sleeker design and I'm sure it's lighter too. Money well spent!

    Totally different feel now that it has been upgraded. I suggest this upgrade because I will not have any issues grabbing the bolt and have it slip off my fingers. The grooves on this Area 419 provides you with that ultimate non slip grasp. This is another one of those…. Get it!

    Great upgrade makes it easy to lift the bolt handle with the index finger
