Vortex strikefire ii - Vortex StrikeFire II 1x30mm 4 MOA Red Dot Sight

For my needs, this was the perfect acquisition for my AR-15. It's optics are clear and target acquisition is immediate. It's easy to use and the price was right. The lens covers work nicely but are opaque. It's light weight and has two colors for its dots (red and green) and at least five levels of brightness for each. If it has a shortcoming, it might be the 4 MOA dot doesn't give precision at 100 yds, but I'm always near the center. For precision, I'd switch to a crosshairs reticle. I'd definitely buy it again.
