Well the stats are correct but most of it is suicides. And only about 250 deaths per year or less from black rifles.
I think the 2014 FBI report said roughly 33000 total of which 11000 were not suicides and called homicides. In tho case homicide included murder, manslaughter, negligence, legal self defense, etc. Of the 11000 about 420 were long guns which includes rifles, ARs, shotguns, muskets, etc.
