How to fit a QD stud or Bipod Sud
- Remove the stock from the action.
- Measure the thead with and core width of the qd stund. Select a drill bit that is just bigger than the core, but smaller than the qd studs diameter
- Secure your stock in a vice that has been padded so that there will not be any vice marks left on your stock.
- Place some marking tap where you intend to drill the hole.
- Mark about 5 cm from the front end of the stock and mark a centre cross. Make sure at this stage that if you were to dill at the marked point that it will not interfere with anything.

- Drill a bit at a time until you reach your mark.
- The place the QD stud with the washer and screw down into place. The stud should not totally swash the washer and the hole of the stud should 90 degrees to the stock.
