Custom machined stainless steel knob kit replaces KWM 3/16” allen bolt. There are some variations on the installation on KWM hardwares into different brands of stocks. With measurements from your stock, I have been able to make it fit your stock. So loose the allen wrench. Also custom height spacer blocks so no more “C” clips to loose. Custom height pillar block machined to fit your requirements. I do custom machining and always enjoy a new challenge in making parts big or small. Check my feedback.
