Area 419 Firearms Bergara/CZ 457 Finger Groove Bolt Knob - 6061-T6 Aluminum Black

The Area 419 419-KNOB-BERG is an aftermarket finger-groove bolt knob engineered specifically for Bergara and CZ 457 rifles. Competition shooters, hunters, and recreational plinkers will appreciate the more positive, controlled bolt lift and noticeably better feel compared to the factory knob.

The signature finger-groove profile seats your thumb naturally so you can cycle the bolt quickly and consistently round after round. Slim knurled grip surfaces add extra traction in cold or wet conditions without being sharp or uncomfortable against the thumb. The result is a clean, ergonomic knob that improves handling without changing the bolt's mechanical function.

Machined in the USA from 6061-T6 aluminum and finished in a durable flat black anodize, the knob is lightweight yet tough and corrosion resistant. It threads directly onto the factory bolt using the correct M6x1 thread pattern for Bergara and CZ 457 actions, with no gunsmithing or special tools required for installation.
