Have tried a number of red dot sights priced up to $ 400.00 and this one stands out.
When using it in bright light and snow the dot remains visible.
In some part this is due to the lens coating but the effect is also enhanced by use of a screw in polarizing filter which was also supplied.
Further enhancing the value is the choice of four different reticules to match different shooting conditions.
Did add a small amount of silicon seal around the edges of the press fit polarizing filter ( Inside a separate screw in mount ) to keep it from popping out.
Use this on a Smith & Wesson .460 handgun with great results.
Due to the low mass of the sight itself the mounting rings do not in my opinion need to be heaver.
Have also tried this on a .375 H&H and .416 Rigby rifle just for fun.
With a rifle it shoots 2-3" groups at 100 yards.
Personally I think the best applications would be for up to 75 yards maximum and most likely 50 yards or less. It really is ideal for .17 HMR. .17 MACH 2, .22LR, .22 Mag and such.
Have fun and be safe in your addictions !
Pros: Works in Bright Light, Cost Effective
Cons: Polarizing filter is snap fit and popped out using a .460 S&W pistol
