This is cool!!  HHA Sports developed and adjustable scope mount specifically for crossbows that allows you to use any single crosshair or single red dot scope and still adjust for different impact points out to 80yrds.  This kit includes pre-calibrated tapes to compensate for bows from 260 to 410 FPS.  Simply install the unit onto your bow and mount your scope.  Set the dial to zero on the factory installed calibration tape and sight in your scope at 20yrds.  Move back to 60yrds and adjust the dial to bring your arrow onto bullseye and read the number on the dial.  This corresponds to a pre-calibrated tape included with the kit that you tape tot e wheel and you are now dead on from 20-80yrds with no more scope adjustment!  Simply range your target, turn the wheel to the range and your crosshair is dead on.  This high quality piece is not "loose" or "wobbly" like other adjustable scope mounts.  Any scope will work on this mount, but we are experimenting with a 44mm Hawke that looks to be a great option for a large retical, high quality scope that will pull in alot of light and give a wide field of view....more on that later...

Fits right hand shooters only...left hand version coming out sometime this summer
