They are clear and once zero, they are excellent. The target style knobs are strictly for zeroing, my brother and I currently own two Viper 6.5-20's. The target knobs are far from repeatable, so if you plan on using it for extended range shooting, using your target knobs to adjust for your MOA in drop. They are not consistent at all. Mine has been back to Vortex for repair and then sent back again for replacement because I could not shoot at 100 yards, dial to my 300 yard zero and back again without it being off. Even after replacement it still isn't even close to accurate on knobs adjustment. Some times I can shoot with my 100 yard zero. Dial my elevation for 300 yards and my first shot will be way low at 300 yards as if I never made the adjustment. Then the second round will be close, it's almost as if it take the recoil of the rifle to make something move inside. My brothers is the same way, his is just sitting, it hasn't been sent back yet due to the fact mine going back and then being replaced hasn't changed a thing, the problem still is there. Completely non repeatable. Once they are zeroed and you dont mess with the scope adjustment knobs they are fine if you wish to just hold over for extended shots. Rather worthless in my opinion.
Im fed up with mine, it has ring marks but if someone thinks they are so great. My 6.5-20x 44 Viper with side focus, duplex reticle, box and all paper work is yours for 200 bucks shipped.
