This red dot easily compares to the more expensive ones in quality by offering several reticles, brightness adjustment, and small size. Be careful of battery drain, as this sight does use batteries at a decent rate. Fantastic and versatile product!

Poor qualtiy. When I got it out of the box I thought it was a pretty nice red dot. Upon looking at it closer, it was canted to one side. The up/down screw broke when I tried to zero it. Cheap Chinese junk....The design was good, but the components are cheap.

I have it mounted on top of my scope for short to medium range fire on my C x 4 Storm. Extremely comfortable to view through and worth it's weight in gold.

When I bought a SU-16 I wanted a red dot that wouldn't break the bank so I tried the Barska AC10632. It's not an OKO but it is functional. It appears to be well constructed and rugged. It's easy to mount and set up. The rheostat knob is easy to turn and the brightness range is enough to cover moonlight thru bright daylight. Once sighted in it holds zero and switching between reticles is easy. A few suggestion that would make it a better sight. 1. A clearly marked off position. It is too easy to inadvertently leave this sight on after a day at the range. I painted white stripes on the body and knob that line up in the off position. 2. A "finder" for the reticle. This is important when using a red dot on a handgun. I tried the Barska on a Beretta Neos and it really slows down sighting when I have to hunt for the the dot. The OKO has a notch at the rear and a little tab at the bottom of the lens ring that together act like a regular sight. This makes it very easy to align ...
