What is your intended use? Are you hunting or punching paper?
I personally have a Bushnell Trophy T-dot scope on mine, mainly because it looked similar to an ACOG. I use my rifle mainly for shooting chickens. I find this scope is lacking for use as a hunting scope. The 1x scope is ok, but a chickens head at 50 yards is awfully small. So small in fact the red dot covers the neck and head of them, making accurate aiming difficult. Also, the dark coatings on the glass make for hard target acquisition in dark shadows. I missed alot of chickens simply because I couldn't see them in the scope. I would have to move my head and find it with my naked eye and move back and try to aim.
I am now looking for a 1-4 or 1-5x scope for my hunting rig.
