Just measured an unboxed Decelerator I had on hand and its mounting holes are about 3.13" center to center. I checked the holes on the factory M12 pad and they are the same. This particular Decelerator is the only black one I have on hand, and is the 3/4" thick model, versus the 1", meaning I'd have to cut less of the M12 stock to get the LOP I want. For a .308 I think the 3/4 thick pad will be fine. Reckon I'll earmark it for this project. The factory pad is not even 3/4", after all.
