i just had a thought i like the winchester model 37 shotgun, is there a way to make the smooth bore barrel i rifled barrel, like by having it rifled or maybe have it setup to take removable chokes or something, i just was curious if it was possible.

By the time you spent the $ on attempting it, you could have bought a new shotgun

Don't know about the rifled barrel ,But I have a 37 that has a model 37 lock up,a model 12 chamber and 36" of water pipe.Shoots the devil out of #9s

I bet it does, my 410 model 37 shoot really good too.

I am not familiar with that model but if it has screw in choke you could put in a rifled choke tube. Whether it works or not is another story.

^ no it dosnt have a screw in choke
