I have a buddy I shoot with that has one. If I remember right he did have some problems with the turrets being hard to adjust or such. He has it on a Savage 300 Win Mag and we shoot a lot of 1000 yd. stuff and after the fix he loves it pretty consistent bulls eyes at a 1000 he usually does under 10 inches with the gun and scope combo.
I got one last week, took it out of the box, and the first thing i checked was the turrets, they felt like they had sand in them, gritty feeling, just horrible. so i boxed it up and sent it right back, and exchanged it for a Vortex Viper.
