Someone recently gave me a Nikon Buckmasters 4-12x50 scope, and I noticed that the reticle looks unusual to me. I tried my best to capture it in the picture below; but if you look closely at where the horizontal line of the duplex reticle intersects with the vertical line, the left side intersects at a slightly higher point than the right side does. This doesn't look right to me, but I'm not an expert on Nikon scopes; so is it possible that this is by design? Or is it more likely that the scope is damaged? Have any of you ever seen something like this?
