3 MOA Red Dot Sight,Dot Open Reflex Optical Sights for Subcompact Pistol with Shake Awake Technology Durable Parallax Free Handgun Sight

Nice unit. Works as designed. Small in size. Fits into the cut out of a S&W .22 Mag. Nice bright dot and the controls work as advertised. Love the Shake Awake.

Installed this sight on my PSA Dagger, and it works great. Fast easy target acquisition and easy to zero. I certainly hope it holds up well for a long time. Quality red dot sight at a great price. It would be nice for it to come with a protective cover like my other red dot sights.

A little trouble getting it to sit flat with just the 2 screws on one end. Pushing firmly on the top of the hood while tightening the screws worked. Nice, bright dot, simple adjustments, and a shake awake makes this a very nice optics, especially for the price.

The placement of battery towards the front prevents the rear screws from securing the unit evenly to the slide. The battery protrudes about a 16th of an inch past the bottom of the sight, as the screws which are towards the rear are tightened the front lifts up. The down adjustment on the sight does not have enough adjustment to lower the sight red dot to be on target. I had to rig the mounting using silicon and nylon washers between the screws and slide to level the sight to slide. Even with this, as its tightened the front stills lifts up, but barely in tolerance to get the dot on target. Also without the rig if the screws are tightened more than snug the unit would go full to max brightness and not allow intensity adjustment, the screws need to be left snug, i think somehow the unit warps when the screws are tight causing some distortion on its circuit board. Also, the red dot is not that defined. I have this on a 22 for target practice and would not use this if reliability is a priority. I have several other brands of units at higher cost, but they are very much better in all areas than this unit. For the future I would never purchase a sight with a battery on the bottom as this is the main cause of the problems. Update: Stopped working at about 250 rounds, started randomly turning off then finally stopped altogether.

It is a nice little red dot, does what it needs to do. Holds well with my vortex venom. Only complaint i had was it didn't have a protective dust cover for it for when it's stored. After research and a few trial and errors. i found the Holosun 507C & 407C HS universal cover fits like a glove with not alterations required to fit.

OK for the price and as a first red sight but wont hold zero. You have to adjust on regular basis, pretty every time you use the gun. Clear lens, bright red dot and shake awake for that price you cannot be too picky

Great little optic for the price. Have it on my shield plus and does great. Fit and function are spot on with more expensive optics.

Lame dot ,finish sucks and good luck using it outside..ya can't see it..buy something else this one blows..
