Does anyone know where I could get a few Hex Head or Torx Head screws to fit the Burris Signature Zee Rings? I'm not talking about the ring caps themselves, but rather the screw that fastens the ring to the rail. They come with slotted screws, and it is difficult to get good torque on the screw with a slotted drive. I'm not sure of the thread, but I'm sure it's a common size like 10-32, or something of the like. Places like Home Depot and hardware stores don't stock specialized screws like this. I thought of Brownell's, but it's really hard to find specialized things on their website. Bill T.
