Swampfox sentinel compact micro - OpticsPlanet Exclusive Swampfox Sentinel 1x16mm Ultra Compact Micro Red Dot Sight

The quality of the optic is fine it's the model I got. I though I was getting the regular old sentinel because that is what was pictured. This one however is the one that auto adjust the brightness. There's no manual way. The site however is always dim atleast to me. Even after I swapped batteries. If you get one make sure it's the manual adjusting model
