I build mostly tactical style rifles but I do put that knob on everything I build. It is a kit from Tactical Operations in California. The barreled action in the second picture is another rifle I'm working on right now. It is a 20" heavy barreled 308. If you look close you can see the threaded section of the bolt handle where the knob screws on. The way I do it is to cut the knob completely off the shank of the handle. Then I drill a hole in the center of the shank and insert a threaded stud and tig weld it in place and grind it down to a nice smooth transition.It is alot stronger than machining the knob down to accept a knob..... Better yet here are some pictures

Here is the kit

Last night I blasted the bolt handle and sprayed the bolt and rings. I baked them a 320 for 70 minutes. All said and done on the small parts I like the Gun-Kote. It is super thin and I beat the bolt on the kitchen counter and there is no marring in the finish
