G&G Bolt knob upgrade kits now available. Upgrade your stock bolt knob to increase your grip on your bolt and get on target faster. Check out the video here.
Works on Howa, Rem700, Weatherby Vanguard, Tikka and CZ.
Bolt knobs fit most standard bolts. Fits bolts with a knob smaller than 18.5mm and a stem smaller than 8,8mm. If its a little loose, add a 10cent to the top and that should snug it up.
