If you are near Northern Virginia, near Winchester, Virginia you can come by and visit and bend your butt stock yourself..... the tool, the rack, is sitting in my garage and rarely gets used these days.... I am fairly sure that your shotgun has a through bolt in the butt stock.... This will make bending this butt stock more difficult..... I would doubt that you can achieve a 3/8 inch cast off...... You can get some but probably not that much..... Good Shooting To You, Jent ..... posted August 11th of 2019.
