Because the Kilo 2000 worked out so well for me, I went and checked out Tango 4 and Tango 6 models at the elite Sig dealer local.
Every one of them they had on display and the ones I asked to check from the back had awful, worthless turrets. The clicks were completely random, like 0.05 mil, then 0.5 mil, then 0.10 mil, then 0.2 mil. The locking turret feature could not be used straight down. In order to lock the turret, you had to push down and then turn 2-5 clicks before it would go down and lock. I could not believe how low quality Sig scopes are. Worse than those $20 chinese ones at gun shows. I thought I'd found a bad one, but it was every model.
If I was Sig, I'd kill off the electro-optics line before it kills the name the Sig name.
