Area 419 Firearms Defiance Bolt Knob - 5/16x24 Anodized Aluminum

The Area 419 Defiance Bolt Knob is a precision-machined drop-in upgrade for Defiance bolt action rifles. Made in the USA from 6061-T6 aluminum and finished in a durable flat black anodized coating, this replacement knob gives precision shooters a more secure, ergonomic grip on the bolt handle for faster, more confident follow-up shots without adding meaningful weight to the rifle.

The signature feature of the Defiance Bolt Knob is its integrated finger groove on the underside, which gives your thumb a positive purchase point so the bolt can be cycled smoothly during competition or general field use. The knob is threaded 5/16x24, making it a direct replacement on Defiance actions and a compatible upgrade for Remington bolt actions or any other rifle using the same 5/16x24 thread pattern.

Whether you are running a Defiance build or simply want to upgrade the handling of an existing bolt action rifle, the Defiance Bolt Knob is a simple, lightweight modification that immediately improves control and comfort at the bolt handle.
