Red Dot Open Reflex Pistol Sight for RMR Cut Footprint, 3 MOA Shockproof Waterproof Red Dot, Durable Shake Awake Parallax Free Sight for Full-Sized Handguns

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.

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.

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

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.

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.

Great Red dot at any price but a bargain here.

Very impressing it’s worth it for the price convenience metal case screws manual and the plates. It’s very good. There is no difference between that device and the other words like for $500 it’s the same. The lens is absolutely perfect and clear it’s worth it. I did compare it with the others. Literally there is no difference. Very easy to install four minutes the most. But unfortunately, it doesn’t fit Wilder BDB full-size ot hk vp9

This works really well for the price. I have not tried other brands, but I am pleased with this ones practical affordable approach pretty easy to site in and seems to stay accurate.
