I have a Vortex Viper 3-15 rifle scope in a Scalarworks mount. The Vortex scope is a first focal plane with an EBR-2D christmas tree style reticle and is a 30mm scope. I have two of these scopes and I don't need both of them. I am asking 550 for the Vortex and 300 for the scalarwoks mount which is also 30mm.
