I am one to own a few guns and like to add something new every once in awhile. However I have little to no knowledge about black guns. My interest is for shooting targets and deer hunting with one. I am not asking which one to buy but what should I look for. Chrome lined barrel or receiver? Mil spec barrel? Flat top or iron sites? I may add a light or forward handle. Hell I might paint it haze grey like a Navy ship. Once I know what I am looking for then I can start looking into a brand to buy. Any helpful advice is welcome.
