He530c sight, well worth the money - Holosun He530c-gr Elite Tube Sight

I've got one He530c and two He530G's, and am thinking about buying another "c" model.
Being made of Titanium, they are about as indestructible as you can get for the body construction. I've got both the red and green version, but prefer the green reticle.
I also like the 30mm dia. lens diameter. I keep thinking of another high grade, tube style sight, but I don't care for the lens only being 20mm in dia. I just prefer the larger sight picture.
The dot shape is about as round as I've seen that people with astigmatism can see. There are MANY not as round for us folks with lousy eye sight ! The "kill flash" piece is a very nice offering if you need it. The "quick Detach" lock has two square lugs and the cross bolt to hold it solidly in place on your rail. That's three means of security solid. The lowest dot brightness setting is very low, so using it in low light conditions is VERY easy. No blown out dots, because of being too bright. The brighter dot setting is also great for outdoor, sunny days.
As far as "dot" sights go, it's VERY difficult to beat this sight.
Ok, so. do I buy another "c" model ?
