Stevens 820B Shotgun Barrel Removal

[mcgill]

I have a Stevens 820B Shotgun with a damaged Barrel. Has anyone ever removed one? if so, how?

Not that particular model, but I have removed a couple. I grip the barrel with oak blocks in a hydraulic press. Pine pitch provides the grip. I believe I bought the blocks and pitch from Midway or Numrich. File/sand the blocks to match the taper of the barrel. I grip the receiver with a Mauser receiver wrench with multiple modifications/adaptations to match the receiver. It’s a challenging task (I’ve failed once), but satisfying when it works.

Thank you. That matches my findings too.

You are welcome! Applying Kroil for a few days doesn’t hurt. Applying heat is pointless. It’s impossible to heat the receiver and keep the barrel cool, so they expand at the same rate.

I finally successfully removed the barrel. For the receiver, I clamped the barrel as close as possible to the receiver. The steel vice is round top and bottom. I inserted aluminum shims, shaped as semi circles, about 1/8-1/4 inch thick, top and bottom. Clamped this down to the bench, very tight. Then I used a "vise wrench", aka receiver wrench, square on both sides, as the receiver is also square on both sides. Clamp this down as close to barrel as possible and tight, not over tight. Then I whacked the receiver wrench counter clockwise (looking from stock end of receiver) with a short handle sledge one time. The parts moved easily on a single whack. Then unscrewed the rest by hand.
