Got em for my VX-II and love em. Mine is on a 7mm-08, and with my zero set at 200 and a muzzle velocity of 2850 with a 140 gr bullet I had enough travel to be able to dial out to 680 yds. Has a zero stop, clicks have been very true, return to zero with no issues, and they are low profile so they dont get in the way. They also send you an extra dial for different loads you may work up. Zeroing is also simple, just sight it in to your zero, loosen a small allen head screw, set your dial to your zero and your done. You wont regret it.
