I've done it but only for myself (I am not even an internet gunsmith). It is a job you can do if you want. Takes some space and the building of a substantial jig, but it is a fun project.
YUP THREAD RELATED
I have a first year Superposed with a Monte Carlo stock, Through the Stock bolt, and a Miller mechanical trigger that i am going to bend.((Cast off)). I have done this before to other shotguns, with"" some success"". I have a good solid jig. In the past I Have used a heat lamp with wet towels. I start slow and work up in side pressure against the side of the stock, Takes a few days.
I would like to get some tips or other information on this procedure. OR MAYBE I am doing this wrong. I would like to hear of others experience with stock bending.
Thanks for reading my post
