Made in the USA from 6061-T6 aluminum and anodized flat black, the AREA 419 419-KNOB-DEF delivers a significant upgrade for Defiance bolt-action rifles. The Defiance bolt knob is threaded 5/16″-24, ensuring a secure fit on compatible actions. This ergonomic upgrade is engineered to improve bolt manipulation speed and control during both competition and field use.
The design centers on a distinctive finger groove feature that sets it apart from standard bolt knobs. The finger groove allows you to manipulate the bolt with just your pointer finger without searching for the ideal position each time, and your finger automatically catches in the groove to assure the fastest, smoothest bolt manipulation. Two knurled surfaces located on either side of the groove give a sure grip, providing flexibility for one-finger operation or full-hand control depending on your preference.
Built with the precision machining Area 419 is known for, this bolt knob transforms your shooting experience by reducing fatigue and increasing operational efficiency. the improved leverage and ergonomic design make this a practical upgrade that pays dividends with every bolt stroke.
