I have an 1894CSS that I want to polish with Mother's mag. But I can't get the darn forearm off. I got the mag tube all loosened (remove cap, spring, screws), and the barrel band screw loose, but that forearm wont budge!
Pull the mag tube out the front, and apply firm pressure as you pull the forend toward the muzzle. The wood probably dried out some and contracted around the barrel and receiver joint. Keep at it, it'll come off. Just don't pry it off!
