Adding an enlarged bolt knob to a rifle is a popular upgrade that give a better grip when operating the bolt under any conditions. You can add this durable enhanced knob by yourself without permanently modifying your rifle.
The Bolt Lift Kit consists of 2 reinforced polymer knob halves and some supporting parts. Users can choose between a permanent installation using epoxy (not included), a rock solid removable setup. or a quick simple install using the supplied spacers to tailor the fit to your factory bolt handle. The Bolt Lift Kit is made of a very strong, reinforced polymer material incorporated into a thick-walled, high strength design to ensure your Bolt Lift will last.
The SV (Small Version) is more compact and sleek. As KRG says "The difference is not huge. There is only so much shrinking we can do with something that fits around the existing Remington handle." The SV also has an enhanced grippy surface to help in adverse conditions.
Installation is simple and can be accomplished with a Hex (Allen) wrench - 5/32".
