The Mountain Tactical Bolt Handle Kit is designed to give you more control over your rifle. The longer handle makes cycling the bolt easier. This allows you to eject and chamber a round without taking your sights off your target. A larger diameter bolt knob increases tactility making positive bolt manipulation while wearing gloves a more confident and safe action. The stainless steel handle stem uses industry standard 5/16-24 threads so you can switch out knobs with ease.
