Good for the price, not great overall. - Burris FastFire II Reflex Red Dot Sight, 4 MOA Reticle, Black, 300233

It would be fine for a gun that is kept in a safe and not expected to perform anywhere but the range. The application I intended to use it for was mounting on a shotgun for upland game. After mounting it and looking through it, I was afraid the dot would be too small and too dim to pick up against a bright sky background. The brightness is not adjustable, it automatically adjusts, and doesn’t get bright enough in my opinion. It would be fine indoors, or in low light. I ended up buying a different optic for my intended application.
