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 Impact is typically preferred for 75 degree bolts but works well for 90 degree also.
