Bushnell’s unit is heavier than some other models at 2 ounces (gasp!), but it works well and is the least expensive one here. It’s got a sensor that shuts the unit off when it’s covered and adjusts for brightness. As with most auto-regulating sights, however, the use of a flashlight at night can confuse it, making it too dim under some conditions. MSRP: $193.
