I wanted a extended/tactical bolt handle for my build so I decided to try and make one. I figured if I screwed it up, I would just order a complete one. I ordered a 5/16-24 threaded knob from PT&G and got a 3" bolt of the same thread. I cut the old handle off at the shoulder, and welded the bolt on. I then used files and sand paper to smooth everything out. I tweeked it to the rear a little and slapped a coat of paint on it.
