Complete junk - Osprey 4-16x50mm Black Illuminated Rangefinder Reticle 30mm Tube Tactical Rifle Scope

This scope is complete junk. Adjustments are no where near accurate, poor light transmission, will not hold a zero. Mounted this on a 308. The first group was 6" right, and 4" low. Made the appropriate adjustments. The next group was 12" left and 18" low. Moved the turrets back to their original settings, and the rifle was now hitting 3" right and 16" high. We finally got it zeroed by tapping on the turrets, no turning, just tap on them. Got one good group. Next time I shot it, it wasn't even on paper.
