The tactical knobs consist of two reinforced polymer knob halves with supporting parts. Use the supplied spacers to tailor fit the knob to the 700 factory bolt handle and the stainless steel screw will clamp the knob halves together using the stainless steel reinforcing pins (instructions are provided with each knob). Installation takes about 5 mins.
They are made with reinforced polymer material and incorporated into a thick walled, high strength design to insure that your tactical bolt knob will be the last part of your rifle to fail. 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 all by yourself.
