The Bolt Lift and Bolt Lift SV for the Remington 700 are the first and only products of their kind. They give you all the benefits of an oversize bolt knob in a simple user installable package. Adding an enlarged bolt knob to a rifle is a popular upgrade that gives a better grip when operating the bolt under any conditions. Previously, if you wanted that improved bolt handling you would have to buy a knob and send your bolt off to a gunsmith who would cut and thread your bolt handle and install your new knob. Now, you can add a durable enhanced knob by yourself, and you don’t have to permanently modify your rifle. Kinetic Research Group KRG Bolt Lift Small Version Black BLS-BLK
