I just got rid of my Mossberg 535 slug gun and am looking to get another. I do have a NEF 20ga smooth bore that I am considering getting drilled and tapped for a scope. I would put a red-dot on it/ I will never have the chance to take a shot over 50yds, so I think the smooth bore can handle it. What do you guys think?

BTW: the drilling and tapping wouldn't cost me anything, the only cost would be the red-dot.

Thanks
