I have a mint/near mint CBE Tek Target sight with a viper scope .10 pin single pin and 3x ziess lens. I used this for the last half of the 2013 season. Maybe 2500 shots with it. I just prefer my viper 6 pin over this one for 3-d and hunting alike. I no longer have time to compete, you can pm your offers. Item is for sale on fb and locally.
