I cannot give the answer as to why remingtons need the recoil pad and the Browings and Savages do not. It must be something different about the deaign that results in a damaged bolt in the remingtons and not in the others.
The pad is held in by a blind rivet that is pretty difficult to completely remove as to allow a new one to be installed the same way. I have seen a few receivers accidentally drilled through the back bu someone trying to remove it.
The few that i have had to do, i have chiseled the old rivet off flush, cleaned the area well and epoxied a new pad in place.
