Reticle

The EOtech 552 A65 1 Holographic Sight features the same A65/1 reticle pattern as the model 512. This is a good thing for a few reasons. Here is a breakdown of the A65’s 3 components:

  1. Tiny 1 MOA aiming dot in the center for precise aiming.
  2. Large 65 MOA outside ring for quick target acquisition.
  3. Four quadrant ticks at cardinal points for leveling.

It’s common for red dot sights to have a 2 MOA dot in the center. This larger dot is more noticeable than the 1 MOA of the 552 model. Meaning, you can line up the dot with your target faster.

The 552 takes a different approach. It uses the smaller center to get tighter groupings. About 1″ at 100 yards for the 552 vs 2″ grouping for a 2 MOA red dot. What you have lost in target acquisition speed you make up for tighter precision.

EOTech made up for the loss in acquisition speed by adding the 65 MOA outside circle. It’s very easy to see. Much easier than the 2 MOA dot. So, at closer ranges, your eye will pick up the target much faster.

With the A65/1 reticle you get the best of both worlds. Pick up your target faster at close range, and more precise targeting at long ranges.

Field of View & Brightness

This sight has a field of view of 30 yards at a 4” inch eye relief and features 30 scrolling brightness settings, ten of which are for night vision usage.

The brightness adjustment range is 146,000:1 at its brightest and lowest, respectively. With the NV switch engaged, night vision compatibility is 1280:1.

Weight, Dimensions & Build

The sight itself has dimensions of 5.6” x 2” x 2.5” with a window dimension of 1.2” x 0.85”, and weighs in at 11.5 ounces. The front window is made of 1/8” inch solid glass while the rear window is composed of 3/16” inches of shatter-resistant laminate.

The display window’s optical surfaces have anti-glare coating.

This EOtech sight was specifically designed for close combat and versatility. It is made of aluminum and is easy to mount without tools thanks to its knobbed bolt.

Battery

The EOtech 552’s battery will last 1,000 continuous hours of nominal use via lithium batteries and 600 continuous hours of use via alkaline. The power source uses two 1.5-volt AA batteries and accepts lithium, alkaline, and rechargeable batteries.

When you fire this thing up, it automatically flashes a battery check indicator reticle.

Weatherproofing

It’s waterproof and submersible up to 33 feet while also sealed for fog-proof internal optics. This is another upgrade from the 512, which is only waterproof to 10 feet.

All electronics used in this device are encased in a shock absorbent resin.

While in operation, it can withstand a temperature range of -20 to 150 degrees Fahrenheit, but while in storage, the sight can handle a temperature range of -40 to 160 degrees Fahrenheit.

Parallax Free

The optics use parrallax-free transmission holography for minimal work to get a clear shot. The EOtech 552 has a 1x magnification to get even more target accuracy.

The major advantage of the 552 over the 512 model is night vision compatibility. The better weather sealing is nice, but you, unless you know you will need it, weather resistance of the 512 is fine.

If you will be using night vision in the future go with 552. It will definitely be worth the additional cost.

Conclusion

All of these great features make the EOtech 552.A65 to be a formidable weapon sight in the right hands. After all, this sight has been standardized by the DEA, ATF, and FBI SWAT team and has been used as a top choice of military units like the Stryker Brigade and 3rd Infantry.

The 552 holds its own in the market. The cost of this rugged sight is well worth the features it boasts as a high end product. Whether used for hunting targets at the range or game in the wilds, this sight will help its users keep their aim true regardless of experience.
