A must-have for selective archers! 3rd Axis Leveling allows adjustment in 3 axis - scope to the sight and scope to the flight plane of the arrow, ensuring consistent right and left arrow impact in conditions from extreme uphill shots to extreme downhill shots. The armored holder encloses the threaded scope rod, the weakest point of a sight/scope assembly, and minimizes the chance of breakage from vibrations. The new hex shape eliminates the possibility of scope turning in high vibration conditions and allows large adjustments without scope rotation. Standard 10/32.
