Brad: To be honest, I don't know. I traded a stock refinishing/checkering recut on a Fox Sterlingworth for the MPI. When it arrived I realized quite quickly that if I squeezed the forend hard I could crush it. Among other problems, the sharp pointed screw that retains the bolt release on a Mauser sat outside the profile of the stock. I keep thinking it was the first one they ever made for a 98. One thing about glass stocks. you can do a lot of modifying to make them work and still look fairly good. This stock is the spare canoe paddle I referred to several months back. I'm more than happy to returm to walnut where you have to do it right the first time. By the way. by the time I had incorporated enough fit and strength to suit me it was no longer a light weight stock. Probably equal in weight to good, dense walnut.
