Area 419 Finger Groove Bolt Knob for CZ 457 and Bergara B-14, M6x1, Black

The Area 419 Finger Groove Bolt Knob was designed to be the best all around bolt knob for competition and general use. Its main feature is the finger groove which allows you to manipulate the bolt with just your pointer finger without searching for the ideal position each time. Your finger automatically catches in the groove to assure the fastest, smoothest bolt manipulation. There are two knurled surfaces located on either side of the groove to give a sure grip.
