Area 419 Firearms Defiance Bolt Knob 5/16x24 Black Aluminum

The Area 419 Defiance Bolt Knob is a precision-machined aftermarket upgrade designed to replace the factory knob on Defiance and Remington bolt action rifles. Purpose-built for competition shooters and hunters who want better grip and smoother cycling, the knob features an ergonomic finger groove profile that gives your thumb a positive, repeatable purchase during fast follow-up shots.

Each Defiance Bolt Knob is made in the USA from 6061-T6 aluminum and finished with a tough black anodized coating that resists wear and corrosion in the field. The knob is threaded 5/16x24, a standard that matches both Defiance and Remington bolt handles, so installation is a simple direct swap with no modifications required.

Designed by Area 419 to be the best all-around bolt knob for both competition and general use, this lightweight upgrade adds both function and a clean blacked-out look to your rifle. Whether you are running a Defiance long-range build or a Remington bolt action, the Defiance Bolt Knob delivers the grip and control you need to keep the bolt running smoothly round after round.
