I have the Conquest HD on a semi lightweight 7RM. It is excellent mechanically, with really nice locking turrets. Optically though, it has a very curved field of view on lower magnifications. I am still deciding if that is a big enough problem to move it on.

The VXIII AO that was on the rifle previously worked well, but lacked field of view at the lower end.

My deer hunting partner has the z5 with the BRH reticle. It is a very nice scope but lacks a turret. The BT version of the z5 is only available with other reticles which are very fine and might be an issue in low light.

The VX6 has a very short tube which may be an issue with mounting.
