Zastava M93 Called the “Black Arrow” when it was imported and sold on the U.S market, this is a .50 caliber bolt-action rifle. It also came in the Russian 12.7x108mm caliber but used a much longer barrel. I don’t know if these are still being brought into the U.S. I haven’t seen any new supply of them. Couple years ago you could buy one for around $3,500.
