I picked up an 870 youth magnum model at a gun show to build for next spring. The gun works fine and has shot well thus far, but I looked up the serial number and it has a W suffix which indicates a 16 ga small frame 2 3/4 according to what I read. The barrel is clearly a 20 ga 3 inch. I was unaware they even made a 16 ga Express
Is this safe to shoot? Does this really mean the receiver is different from the barrel?
Any help would be appreciated
