Over here in NZ there is a debate over so called Black rifles? Here are mine, from top to bottom, Custom 338LM, 300WM XCR long-range Rem, 308 Tikka tactical, and a 308 Swiss arms SHR 970 alpine.
EN101, I think it's a play on words. The "black rifle" is the AR15 which causes all the debate and drama in the news and politics. These are his "black rifles." Unless, I stand corrected because I too am interested.
