Features To Consider Before Buying

We will start by guiding you through the most important features to consider before buying a cheap red dot sight. You must understand that there are different features for different users, depending on what weapon you have, or where you plan to use it. Therefore, read all features carefully and analyze them in detail to have a better perspective when you start digging into the models.


Let’s start form the core of the subject; all red dot sights have a projections, which can be either a reflex projection or a holographic projection. A holographic projection consists of the sight getting illuminated from the front of the lens, where then a laser light projects onto the viewing window which creates a red dot.

Red Dot Projection

When it comes to the reflex sight it is a bit different. This projection model reflects an LED light, which is behind the lens, into the line of shooting. The reflex sights are more common than the holographic ones, and they consume less battery life.

Weapon Mounting

All red dot sights need to be mounted into your weapon, and most weapons have one of the two most common rails: Weaver and Picatinny. Therefore, check you gun rail, then the sight, and see if one fits the other. If it doesn’t don’t panic, is as simple as buying a mount that suits both sight and weapon.

However, f you have one of those two rails, then most of the red dot sights will fit perfectly. There are still some models that fit just one, and it is commonly the Picatinny, as many models have a built-in mount, but you can just replace it to fit your Weaver rail.


Weight is a key factor for red dot sights and pretty much any weapon, especially if you are dealing with rifles or bigger guns. After shooting many rounds it will be quite normal to feel tired. That’s why you don’t want to add too much extra weight to your weapon with a heavy red dot sight.

Clearly, they all weight something, but make sure it’s a weight you feel comfortable with, and not something that will also alter your “feel” with your weapon. For example, a very heavy sight might even cause you to change the way you shoot.


The reticle is the red or green dot that every sight reviewed in this article has. Now, that doesn’t have to be precisely a dot, as it can also be another pattern. As a matter of fact, many sights advertise themselves as having different reticles, commonly four.

Red Dot Sight Reticle

This means that they offer four different patterns of red or green dots. It can be a bulls-eye pattern, a star, or a more scattered pattern. The idea is to give you the option to choose what you seem to notice better.

MOA (Minutes of Angle)

The MOA (Minutes of Angle) is one of the features included in the table above. It is a measurement that basically consists of a spread of 1 inch per 100 yards. Basically, through the MOA you know in the first 100 yards your red dot sight is very precise.

Red Dot MOA

The bigger the MOA, the more precise your sight will be, as for larger distances, it still has a good spread. However, if you are not going to shoot from very far distances, then a very large MOA will not really influence you.

  • Auto shut off to save battery life
  • Good protection of the lens

Vokul Tactical 4 Reticle Red Dot Sight

Price: Approx. $42Vokul Tactical 4 Reticle

Weight: 8 ounces


Specific features: 4 reticles, 7 brightness settings, an Allen head screw type for windage and elevation adjustments, unlimited eye relief and parallax relief, built-in mounting base for Picatinny rail.

The Vokul Tactical 4 Reticle Red Dot Sight red dot sight is not only a less expensive sight than most of the others, but also a bit more basic, which makes it ideal for beginners or for less complex weapons.

Nonetheless, it is still a fairly good cheap red dot sight. It comes with four unique reticles, which give you good patterns to choose from. It has 3 MOA clicks for better accuracy. It is very lightweight, so you won’t be having much added weight into your weapon.

Plus, despite being a basic or a less expensive model it still has five brightness features, which are still good enough, especially when used in darker situations, not as much under brighter lights.

The biggest concern is the quality, this red dot sight is not the most rugged or resistant sight, and some reviewers have complained that after firing a few rounds it actually either fell from the weapon or was even damaged or stopped working. For the price, it serves the purpose of helping beginners know how to use a red dot sight, or for a quick day at the shooting range, but it’s not very reliable for more experienced shooters.


  • Cheap
  • 5 brightness levels
  • Good unique reticles

  • Not very strong or resistant

Price: Approx. $50Field Sport Red and Green Micro Dot

Weight: 4 ounces


Specific features: Comes with four reticles, lightweight and waterproof and shock proof, Picatinny rail mounting system, parallax designed red dot that eliminates need for centering.

The Field Sport Red and Green Reflex Sight has both a red and a green dot, allowing you to choose which color is easier for you to differentiate. It also includes four reticles, to choose from four different patterns.

It comes with a built-in Picatinny mount base, but if you use a Weaver, you will need to purchase a separate mount. It has the advantage of being not only affordable, but one of the most lightweight models, so if you don’t want to add much weight to your weapon, this is a good choice.

It only comes with a dual brightness control, that despite being a good one, it is fairly basic compared to other red dot sights with more adjustments. The good thing is, that with the parallax designed red dot, you can keep it centered the whole time without needing to make many adjustments. Finally, it has an Allen screw to adjust the windage and the elevation

Bushnell Trophy TRS-25 Red Dot Sight

Price: Approx. $70Bushnell AR Optics

Weight: 3.7 ounces


Specific features: HD clarity on optics, eleven brightness settings, mounts both Picatinny and Weaver rails.

The Bushnell Trophy TRS-25 Red Dot Sight is a great red dot sight, very lightweight and ideal to mount easily on Weaver style or Picatinny rails. It comes with a manual to teach you or guide you how to mount it, but it isn’t very clear according to a few reviewers.

However, it’s not a complicated operation, simply use an Allen style cross screw to secure the sight to the gun’s rail, then the clamping system will provide an adequate strength that will keep the sight securely mounted. Then, to tighten it, you just need an additional quarter turn.

This red dot sight has premium HD clarity optics, meaning you will have a great and bright image even in darker settings. It comes with a technology called Amber-Bright optics, which will help you distinguish between black or brown colors, something that complicates under bright lights.

The red dot comes with 11 settings, the eleventh being the brightest, and reviewers have even said that the eleventh setting is even too bright and you might never need to use it.

Another very interesting feature is that the eye relief is unlimited, and so you can use both eyes open at the same time whilst looking into the sight. This obviously increases not only your accuracy, but also the speed in which you locate the target.


  • HD clarity optics
  • 11 settings to adjust brightness
  • Fit both Weaver and Picatinny rails

  • Rubber dust covers aren’t robust enough

Related: The TacStar Tactical Railmount is a good addition for those who like to have the red dot sight placed a bit higher than usual. It also fits perfectly any Picatinny rails, and it comes with a sidesaddle to store extra bullets.

Weight: 4.5 ounces


Specific features: Eleven brightness settings, multi-coated and scratch resistant lens, waterproof, shockproof, 50 000 hours of battery life.

To begin with, it has eleven brightness features, and all of them are excellent. If you find yourself under the brightest lights on a shiny sunny day, the red dot will be visible, just as if you find yourself at dusk in a tricky light setting, the dot will also be visible.

GERO Tactical Red Dot Sight

Price: Approx. $50GERO Tactical

Weight: 6.4 ounces


Specific features: Water resistant, shockproof, built-in Picatinny mount base, 4 reticle patterns.

The GERO Tactical Red Dot Sight is a good and accurate item. It stays zeroed for many rounds, and it can take a heavy punishment. This might be surprising since the price is quite low, but this just makes it a very good cheap red dot sight. As said, the shockproof feature is actually quite excellent, making it a heavy-duty sight too.

It has a good eye relief, and the reticles can be adjusted into four different patterns for a clearer spotting, as well as adjusting the brightness settings.

The mounting is very easy as it comes with a built-in Picatinny mounting. If you have a Weaver rail and want to use this sight, you will need to buy a separate mounting for Weaver rails and just use that instead of the built-in one.

The only downside is durability. Reviewers find this an excellent sight for the price, as it has many features that only more expensive sights have. However, after a few weeks of use, the sight might stop working completely.


  • Price
  • Heavy duty, can take a lot
  • Built-in Picatinny mount

  • Not very durable

Feyachi Reflex Red Dot Sight

Price: Approx. $60Feyachi Reflex

Weight: 4.1 ounces


Specific Features: 33 mm aperture, water proof, shock proof and fog proof

The Feyachi Reflex Red Dot Sight is probably one of the cheapest red dot sights available in the market. It is also a very good sight for a very good price. It is lightweight, ideal for heavy weapons, as you will barely feel it, or for smaller guns too.

Mounting it on a Weaver rail is a very easy procedure, being one of the easiest sights to mount, dismount and handle overall. The windage and elevation adjustments are also a walk in the park. It comes with a battery, which is one of the few downsides of this sight, since the battery life tends to run out fairly quickly according to reviewers.

Other features include the good 33 mm objective aperture, and the four reticles, which give you four different patterns to choose from, guaranteeing you that you will quickly spot it for a better shot, especially when you have to act quickly.


  • 4 reticle patterns
  • Very easy to handle
  • Lightweight
  • Affordable

  • Not the best battery life
  • Might not be ideal for more serious shooting as the shock proof feature isn’t as reliable as in other sights
