   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.

   The SECDES 3 MOA Dot Open Reflex Sight offers a reliable and affordable option for upgrading your firearm’s sighting system. While it may lack some of the advanced features found in higher-end models, it delivers solid performance and durability. The clear, bright red dot reticle is easy to acquire and track, making target acquisition quick and efficient. While the build quality is decent, it may not be as robust as some premium options. Overall, the SECDES 3 MOA is a great choice for budget-conscious shooters looking to improve their accuracy and speed.

   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.

   Seems to work well. Auto on and off is good.

   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.

   Says it fits RMSc but couldn’t get it to like up on the posts. Tried fitting to a Taurus tx22 toro full size gen 2.
