Hi, I'm looking for a barrel to put back on the action of this Winchester 840. The barrel of my 12ga 840 can latch on the pin but doesn't lock all the way and the gun can't be cocked. I thought maybe it's in 16ga or 20ga. Any of you got an idea on how to find out? Maybe with the serial number it could give it out fir some of you guys.
Thanks
