This Knights Manufacturing SR15, PRI Mark 12 Mod 0 clone is in excellent condition. It shows almost no evidence of use. The previous owner reports that it was unfired. It has a fully ambidextrous Knights Armament SR15 lower, PRI Mark 12 upper, Knights bipod adapter and Harris SBRM bipod. The original Mark 12 Mod 0 SPR was a designated marksman rifle fielded by U.S. Special Forces. This clone is a great addition to any collection and a way to pay tribute to our Special Forces personnel.
