If there isn't already a hole in your magazine cap, you can easily drill one or have a GS drill it. They you can buy the threaded stud and nut to install. The rear is simply a coarse (wood) thread that goes into the stock about 2 - 3" from the end. A bit of advice - when you install the front swivel stud via a nut, peen the edge of the stud a bit so the nut will not back off completely.
