You may not know this but I have a interest in US sniping history. While looking at something else on ebay the other day,I came across what may be a pretty good deal. A US M49 spotting scope.
Coming with the carrying case this is a pretty good idea on the surface. It’s missing the brass plate that IDs it though and pictures show some really rough looking lenses. These are very solid durable spotting scope though. They were used from WW2 all the way up till the 00s. My friend still uses one for LE sniping duties. If you can get one at a good price they are worth every penny.
