I have looked around before at bag riders offered by multiple different sellers in the past, but I have never found anything that I liked. So awhile back I decided to make my own that I think turned out pretty good. It is a slip-fit design that locks into place without any tools. Also it matches the length of the bottom of the RPR stock pretty well, which I really like. I have an angled version as well as a flat version. The angled one is much more useful and looks a lot better in my opinion. I just barely found this forum today, otherwise I would have posted this project earlier.
