Tristar semi auto 12 gauge
A Guy I work with bought a used tristar and wants to put a plug in it, so he can use it to hunt with. He can't figure out how to get to the mag tube to insert a wood dowel. I know nothing about semi auto shotguns or tristar. I looked on utube and couldn't find anything. Any help, advice or info on this would be greatly appreciated so I can pass it along.
