Area 419 Firearms Defiance Tenacity/Elite Bolt Knob Adapter - Black Nitride

The Area 419 Firearms Defiance Tenacity/Elite Bolt Knob Adapter is a precision-machined aftermarket upgrade for owners of the Defiance Tenacity and Defiance Elite bolt-action rifles. Machined in the USA from 6061-T6 aluminum and finished in a tough Black Nitride coating, it gives your bolt handle a more comfortable, repeatable grip for fast follow-up shots.

Threaded 5/16"-24, the adapter installs directly onto the factory bolt body of the Defiance Tenacity and Elite rifles. Area 419 designed the knob around its signature finger groove profile, giving your thumb or palm a positive purchase during cycling whether you shoot from a bench, prone, or in competition. The low-profile shape keeps the knob from snagging on gear while still offering a substantial surface area to operate the bolt quickly.

Area 419 is well known in the precision rifle community for pushing the limits of CNC machining and accessory design, and this bolt knob adapter carries that same engineering-forward approach. Whether you're building a competition rig, a hunting rifle, or just want a more ergonomic bolt handle on your Defiance action, this is a simple, bolt-on upgrade that requires no gunsmithing.
