The original optic in the cross bow package failed and I found the Hawke in a local shop. It has a turret to dial in the yardage instead of three horizontal crosshairs. The accuracy of the crossbow was challenging my skills and extended range sessions was taking a toll on my shoulder. The frog (flipper looking device that holds the bolt) broke with all of the shooting I was doing to be consistent with the equipment. When I replaced the frog I look an afternoon to mount the optic more precisely. I am back to higher than expected accuracy with the package and watch out next season.
