EOTech 512.A65 Tactical Holographic Weapon Sight

EOTech 512.A65 Tactical Holographic Weapon Sight

Materials – The EOTech 512.A65 Tactical Holographic Weapon Sight is a great starting point for anyone new to the EOTech world. It is not night vision capable, but is reliable, durable, and provides incredibly fast target acquisition. The body is made of rugged aluminum, and the adjustment features are standard and easy to use. The windage adjustments have a click value of ½” at 100 yards. It mounts directly to a Weaver or MIL-STD 1913 rail, and doesn’t require any tooling for attachment. This AR 15 Holographic sight accepts 2 AA batteries, but it also accepts lithium, alkaline, or rechargeable batteries. The battery life has a runtime of 1,000 continuous hours (lithium) or 600 continuous hours (alkaline) when ran at a level 12 brightness setting. In fact, there are 20 brightness settings in total.

Performance – The EOTech 512.A65 Holographic Weapon Sight has a lot of standard features that come with EOTech, so it’s a great starting point for anyone who hasn’t purchased a sight from this company before. The incredible picture and capabilities of this sight come standard with all EOTech products, including the long battery life and surprising versatility. This model is a little heavier than many other options, but it still weighs well under a pound. However, it’s also much cheaper than many other EOTech options. Even better, despite the professional-level features, the 512.A65 model is easy to install and adjust as needed.

What we say – The EOTech 512.A65 Tactical Holographic Weapon Sight costs around $430 online. You may be sucking your teeth at that price, but this is the cheapest option that we’re featuring within this review. Like we said before, start here if you’re new to EOTech.

Pros
  • Lowest cost
  • 20 brightness levels
  • Accepts AA, Lithium, Alkaline, and Rechargeable batteries
Cons
  • Heavier than other models
  • Not night vision capable
 
EOTech EXPS2-0 Holographic Sight

EOTech EXPS2-0 Holographic Sight

Materials – The EOTech EXPS2-0 Holographic Sight has recognizable features with some not-so-standard details that you see amongst other sights. The familiar aluminum housing helps protect this sight from shock, water, and fog. It’s even capable of being submerged in up to 10 feet of water without taking damage. This AR 15 sight takes a 123 Lithium battery, which can run continuously for up to 600 hours without failing on the level 12 brightness setting. Again, there are 20 levels of brightness total. There are two small buttons on one side for adding a magnifier, a popular accessory to attach to EOTech sights. The EXPS2-0 model is all about taking up minimal space, requiring only up to 2 ¾ inches of rail space. The mount is locked and released by the use of a quick detach lever.

Performance – If you’re more concerned with rail space and eye relief, then the EOTech EXPS2-0 Holographic Sight is a good option for you to look into. Not only does it take up a pretty minimum amount of space on top of your AR 15, but the quick detach lever makes this a particularly convenient accessory to install and switch around as needed. This also implies that your eye relief is essentially unlimited. If you’re less concerned about the type of battery your sight is taking, then a single lithium battery will keep things less complicated. Plus, 600 hours of battery life is still a very long time to go before needing a new one.

What we say – The EOTech EXPS2-0 Holographic Sight for your AR 15 costs either just under or just over $550, depending on where you purchase it from. If you like compact sights, then look into this model for your EOTech needs.

Pros
  • Waterproof up to 10 feet
  • Single battery with 600 hours of life
  • Takes up minimal rail space
  • Quick detach lever attachment
Cons
  • Less battery life than other models
 

EOTech EXPS3-0 Holographic Weapon Sight

Materials – Similar to the EXPS2-0, but not quite the same, the EOTech EXPS3-0 Holographic Weapon Sight offers true two eyes open shooting for fast target acquisition, as well as a 7mm, raised base for iron sight access. It also has night vision capability, which means this model also has 30 brightness levels: 20 for daytime and 10 for nighttime. The brightest level during sunlight is 146,000:1 and the brightest level during the night is 1,280:1. There are side buttons and an adjustable quick detach lever for easy installment. It attaches to Weaver or MIL-STD 1913 rails. A single 123 Lithium battery powers this model for up to 600 hours of continuous use on the standard brightness level of 12.

Performance – If you like the small amount of rail space the compact EXPS2-0 took on your AR 15, but you want the night vision, then the EOTech EXPS3-0 Holographic Weapon Sight is going to be your best friend. There are 30 levels of brightness to get acquainted with, but there’s nothing wrong with taking a little time to play with your new toy. We also really like the 7mm raised base, so iron sights can be used. Again eye relief can technically be unlimited, so there’s very little inconvenience to worry about. Again, you could practically go swimming with this sight, and nothing would happen to it. The only downside to this holographic sight is the high price tag.

What we say – The EOTech EXPS3-0 Holographic Weapon Sight costs up to $800 online, making it the most expensive option within this review. That price is paying for a compact size, hundreds of hours of battery life, and a practically impenetrable body.

Pros
  • 30 levels of brightness
  • Just as compact as the EXPS2-0
  • Quick detach lever
Cons
  • Most expensive option

Gun Gear Depot EoTech Replica

Materials – The EoTech 558 3X Red Dot Scope is a cheap but reliable accessory for your AR-15. It uses aluminum material for its entire housing, adding to the sight’s high durability. Also, the said material shields it against natural elements like water and fog. Operated by one CR123A battery, this allows it to run up to 600 hours of continuous use. It has resettable windage and elevation adjustments. Thus, you can change the adjustments however you like. When using this sight, you can get up to 3X magnification and 7.3 degrees field of vision. To add, you also get to have 2.2” of unlimited eye relief. It comes with an integrated 5/8″ 20 mm Weaver rail for easy installation. The sight also has an ambidextrous switch orientation. This allows you to mount it on your gun using your left or right hand. It weighs 6.10oz and has a length of 3.9”, making it small and portable to carry. Besides AR-15 rifles, this sight can fit all HWS models with a 7mm riser. Black, pink, and red are some of the color samples you can choose for this sight. In brief, you can get all these superb features with a sale price of only $74.99.

Performance – Whether you’re indoors or outdoors, the EoTech 558 3X Red Dot Scope is your AR-15’s best buddy. Like other EoTech products, this sight can give you the highest picture resolutions. Plus, its waterproof and fogproof attributes make it a perfect sight to use during foggy or rainy days. Not to mention, it can accommodate HWS models besides AR-15 rifles. Hence, its compatibility with other firearms makes it an all-around gun accessory. With an ambidextrous switch orientation, you won’t have a hard time turning it on/off. Also, its given dimensions make this sight easy to carry around and mount on your gun. The only complaint we have on this sight is that it’s difficult to adjust the leverage downwards. It can take you several times before you can adjust it to your desired position. Other than that, this is a decent AR-15 sight with dependable scope features and long battery life. 

What we say – The EoTech 558 3X Red Dot Scope is the best value product included in this review. You can find many online shops selling it for under $100. Despite its affordable price, it’s still a premium accessory for your AR-15. If you’re all about both high-quality and inexpensive AR-15 sights, then this is worth your gun and money.

Pros
  • Unlimited field of vision
  • Is waterproof and fogproof
  • Lightweight and compact
  • Easy to install
  • Very affordable
  • Compatible with HWS models
  • Available in various colors
  • Long battery life
  • Switch orientation is ambidextrous
  • Comes with an integrated Weaver rail
Cons
  • Leverage a bit difficult to adjust downwards
 

Our Favorite EOTech for AR15

Our choice for the best AR-15 EOTech sight goes to the EOTech EXPS2-0 Holographic Weapon Sight. This sight was one of the smallest and lightest options, which we find ideal for hunters and competitors who will be utilizing their rifles for long durations of time. We also wanted to stay in a medium price range (for EOTechs, at least). While the EXPS3-0 model does have night vision capabilities, 20 levels of brightness is a lot all on its own. Even if you’re hunting at dawn or dusk, the EXPS2-0 should suit your needs. If you want to try something not nearly as good as a real EOTech, but still pretty fun, then go for the Gun Gear Depot EoTech 558 Clone for only $74.99.
