Di optical fc1 - DI Optical FC1 Red Dot Sight

I purchased the FC1 holding my breath since it is a relative new military rated optic on the civilian market. That doubt is gone when I received it. It is solid, rugged, and easy to activate and sight in. I love the intensity levels of the red dot prism with the stigmatism in my dominate eye, I have no problem with a crisp sight picture. I would be remiss if I didn't say it also looks good on my platform! It's all business developed by a allied country who has the extremes in weather conditions that this product passed for service use in it's own armed forces.
