Sturdy, tough - Holosun HS407C X2 1x 0.63x0.91mm Reflex Red Dot Sight

I purchased this optic for its rugged build and reliability. I use this on my duty pistol. I don't care for the solar panel since I dont use it. I'd rather replace the battery then have it adjust brightness on its own. This optic gets low enough for night vision and bright enough during a sunny day in the winter when it's blinding. Best part is the battery placement. Don't need to remove the optic to replace battery like the RMR. Highly recommend it.
