So I bought a Marlin 788 yesterday tested it at the range with no problems (after buying two shotguns from the same store in two days and having to return them both for being messed up, long story) it's in like new condition but I'd love an 18 inch barrel for it, but since it's so nice I don't want to just saw it down. I tried to look up information on it online but nothing came up for this gun on google, I was hoping I could get some information and maybe find a place to buy an 18 inch barrel if possible. Anyone know anything about these?
