Hi, I am offering Oversized bolt handle installation.
This is done the right way on a milling machine. We first mill the existing bolt handle down to spec. Then thread the new knob onto the machined bolt handle for a precise trued fit guaranteed. See pics, these are nice and offer smoother chambering and feel. Price is $100 which includes knob and shipping back to you. All we need is your existing bolt assembly. Turn around is one week.
I also turn and thread barrels on a lathe. Barrel threading is $45 shipped back to you if the barrel is taken from firearm. Threaded barrel shown is a Ruger 77/22 22lr stainless 1/2x28.
