Replacement bolt knob for your precision rifle receiver. This knob adds significantly more weight than your factory Kelbly's or Impact bolt knob. Increasing the diameter, length and weight drastically increases the leverage which makes your up-stroke seem softer, smoother and faster. Cerakote black, raw stainless or raw brass finish.
The Extended Knob, originally made for Kelbly's bolts, also fits the Impact 737 and is typically preferred when using the 75 degree bolts for increased leverage.

Bolt handle
Got the Impact extended raw stainless. Machining is excellent and the diameter perfectly matches the joint. I feel like the increased leverage helps keep the crosshairs on target when cycling during a match.
