Posted this in shotgun forum but thought it might belong here. I have an older Stevens 5100 double in 16 gauge, nice shooter, except the firing pin hole on one side broke out. Receiver is now basically useless. My question is will my 5100 barrels fit on a 311 receiver of the same gauge with no fitting? I would like to salvage my barrels and wood. Would try to find something with different choke and barrel length than my 5100 to be able to use both barrel sets on the 311 receiver.
