These bolt knobs were designed by Area 419 to be the best all around bolt knob for competition and general use. Their 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.
