The Viper Connect is a most revolutionary hunting scope. Being a short eye relief scope it offers an amazingly wide field of view – almost double at 10X compared to a normal scope. Great features like the twist-adjust eye relief, built-in click stop at 10X zoom,and the integrated objective lens cover.Designed to be used very close to the shooter’s eye it is not suitable for recoiling rifles. PCP air and 22LR only.
