H. Politik: If I'm getting the right picture you have a pretty common issue. Take a few hours (days) and search within the forum for threads related to forend repair- there are lots and lots. If you study up you can probably repair it yourself, if so inclined. Sdaly, I seem to find serious forend issues in approx one out of three No. 1 and No. 4 Rifles I purchase. I've been bale to repair a few that I thought were finished thanks to the info here. Good luck and welcome to the forum.
