Tang of Fox Airsoft talks about the ASG Archwick Mk13 Mod 5 & Mod 7 Airsoft Sniper Rifles that they have available at their store... "If you are serious about sniping in airsoft, your options for rifles is to either build one or buy a completely built one. The completely built options so far that a lot of people ask about have been kind of hit or miss. ASG and Archwick bring to us a fully built, heavy weight, realistic feeling option in the Mk13 Mod 5 and Mod 7 sniper rifles."
