My favorite bolt knob design - Area 419 Bergara/CZ Finger Grove Bolt Knob

Originally picked this up as a recommendation on the forums for a CZ 457 bolt knob upgrade. The original ball knob was fine, but this is a massive improvement. The position of the finger grove makes lifting the bolt much easier and more natural. Your index finger just lifts up off the trigger and lands right in the grove. Closing the bolt also feels very natural as your thumb catches in the grove nicely. I like it enough that I ordered the same knob for my Vudoo 360 (Area 419 Defiance Finger Grove Bolt Knob 419-KNOB-DEF)
