Set and forget - Holosun Carry Solar Charging 1x16x23mm Reflex Green Dot Sight

This optic may not have the biggest window, but it excels at its designated task...being a great optic for EDC. It is solid and durable, with the enclosed design ensuring that it won't get filled with lint and dust. The green reticle and dot are highly visible in all conditions. The auto brightness ensures that you never have to worry about changing that setting. The mounting design and a little Loctite on the screws mean that your zero setting holds permanent. And best of all, you never have to change the battery or worry about the dot being there if this thing sees just a tiny bit of daylight once every couple years. It truly is a set it and forget it optic and it's just right for a carry gun.
