McMillan uses wood screws on them. You can get a nice stainless wood screw or an 8-32 brass insert and epoxy it in. When installing something that will be under a potential side load like an adjustable butt system, I prefer a long wood screw and also epoxy the plate to the butt, thats the strongest setup.

Thanks Alex this is a b**** gun and I have a removable weights underneath the plate so I'll need access but it seems like I do remember my inserts being brass on the other stocks that were Factory done I will look on McMaster-Carr site to see if I see brass insert if so I'll get some on the way

I use this style, https://www.mcmaster.com/threaded-inserts/tapered-heat-set-inserts-for-plastic-7/
They are only as strong as the material you are epoxying them into. If your relying on them to hold in a few pounds of lead, just handle the rifle carefully and you should be fine. Drop it and they will likely rip out with the stock fill material attached.

This is what I did to install a but plate on a McMillan stock.
1) I put masking tape around the stock in the cut off area. I stood the stock vertically on the butt and used a 1/4" spacer or desired thickness and drew a cut off line on the tape.
2) I hacksawed the desired amount leaving a little to hand finish with file, sandpaper or belt sander.
3) I stood the stock on my aluminum blank and scribed a cut line. Rough cut the plate.
4) I applied thin layer 1/8" to 3/16"of JB Quick Weld to stabilize the center tube and the foam fill.
5) After drilling and countersinking the holes in the but plate I used brass 8/32 threaded inserts for wood from Mennards. I assembled them on to the butt plate. Use screws that do not extend past the end of the threaded inserts or cut the longer ones off flush.
6) I then bedded the butt plate assembly onto the butt by filling the remaining cavity with a light weight auto body filler similar to bondo. Use your favorite bedding release material.
7) Finish fitting the butt plate, polish it and you are on your way.
