Early results are favorable - Vortex Defender-ST Enclosed Solar Micro 1x22.5mm Reflex Red Dot Sight

Fairly durable, as it was slammed/dropped while attached to a carbine and survived without apparent damage. Time will tell if it holds up well, but the first 70 or so rounds through the platform yielded confidence. The adjustments are difficult to feel/hear, but otherwise seems to live up to the description thus far.
