The Kinetic Research Group Bolt Lift SV Black is a small, oversized bolt knob system designed specifically to enhance the factory bolt handle on rifles such as the Remington 700. The kit includes two reinforced polymer knob halves, spacers, a stainless steel screw, and reinforcing pins that clamp securely around the original bolt handle to provide a larger, more controllable gripping surface.

This accessory is ideal for shooters who want smoother, more confident bolt manipulation during range sessions, hunting, or precision training without sending their bolt to a gunsmith. The thick-walled polymer construction not only delivers strength and durability, it also helps insulate your hand from cold or heat. With multiple installation options—permanent epoxy, solid removable, or quick spacer-based setup—the Bolt Lift SV Black offers a flexible upgrade backed by Kinetic Research Group’s thoughtful design and attention to detail.
