This sight fits in at the lower end of EOTech’s holographic sight product line. Not to say the 512 isn’t a great sight – it is. It just doesn’t have some of the bells and whistles the others have. Some sights are smaller and lighter than the 512. Others are night-vision ready. If you don’t feel like paying for these extra features, the 512 is a fantastic sight at a solid price.

Let’s break the 512 down feature-by-feature:

Reticle

The EOTech 512 A65 features a 1 MOA aiming dot inside a 65 MOA circle reticle. This is known as A65/1 reticle pattern, which is made up of 3 parts:

  • 1 MOA dot centered on the outside ring.
  • Large outside ring with 65 MOA (Minutes of Angle)
  • 4 quadrant ticks at the North, South, East and West points of the outside ring

The 1 MOA dot is about half the diameter of the 2 MOA dot found in your typical red dot sight. The smaller dot gives you more precise targeting – pretty handy at longer-ranges. However, it’s not as easy to find as the 2 MOA dot. This slows down your target acquisition a bit.

This is where the outer ring becomes important. It’s a large circle, which makes it very easy to see, and gets you on-target fast. This is perfect for close quarter combat situations.

It’s the best of both worlds with the outer circle for rapid target acquisition and the 1 MOA center dot for precision. You should be set up to 200 yards. Add in a magnifier and you could take that out to 600 yards.

Field of View

It has a field of view of 30 yards at a 4” eye relief so this offers a great visibility.  The brightness range starts at 110,000 at its brightest to 1 at the lowest. There are 20 different settings so you can control the brightness at any time according to your needs.

Night Vision

The 512 does not work with night vision. However, its big brother, the EOTech 552, does work with night vision.

Weight & Dimensions

First, we will talk about the size of this model. The dimensions are 5.4”X2”X2.5” inches and weighs 10.1 ounces. The optical surfaces have an anti-glare coating and the window dimensions were 1.20” X 0.85” inches and the front window material was made from 1/8” solid glass and the rear window is made of shatter resistant laminate that is 3/16” thick. The unit itself is made from strong aluminum hood assembly and a very easy to used knobbed mountain kit.

Battery Life

Lithium battery life is over 1,000+ continuous hours at nominal setting 12 and 600 hours using alkaline batteries. When you turn on your model 512, which takes two AA batteries, it will automatically show you how much battery you have left. It’s good practice to change your batteries regularly, even if you haven’t used your sight. Then you know it will work when you need it.

Water Proof and Fog Proof

The EOTech 512 is waterproof and is submersible up to 10 feet, so if you ever drop your it in a puddle, you can be rest assured that the scope will keep on working.  It can also able to withstand temperatures from -40 to 140 degrees F.

It also has internal fog proof optics to help keep fog to a minimum so you are looking through clear glass – no matter the weather.

Parallax Free

The optics are parallax free so you will never have to center your scope and you will always get a clear shot of the item you are going to shoot at.  The magnification level on this unit is 1X so you will be able to get even closer to whatever you are shooting at whether it is an animal or target.  You will be able to mount your scope onto any hand gun or shot gun with ease and onto interfaces to 1” Picatinny or Weaver Rail.
