Bright dot, clear glass - ADE Advanced Optics RD3-006x 1x Reflex Green Dot Sight w/D1 Rear Optic Mount Plate

The first thing I noticed was how clear the lens looked compared to some other optics I've owned. The blue dot appears crisp and doesn't bloom much even at higher brightness settings.

I've used it during sunny afternoons and cloudy mornings and had no trouble seeing the reticle. The aluminum housing feels durable and the optic has maintained its settings without issue.

For anyone looking for an affordable reflex sight, this one is worth a serious look.
