Are you searching for a budget-friendly dot sight for competitive race guns? Do you need it for fast target acquisition? If so, check out this red dot sight from C-MORE Systems.


Fast target acquisition appears to be one of the main selling points for most dot sights. The majority of brands don't pay a lot of attention to the quality of their dots, though. That's not the case with C-MORE Railway dot.

 6. TRUGLO Tru-Brite Red Dot Dual-Color Multi Reticle Black

buy here


If you're in need of a convenient, easy-to-use red dot sight for fast target acquisition, then this Truglo model is something you definitely must check out. One of the first questions that come to mind with regard to this dot sight is maybe what will it be used for? Basically, it is intended for all-round, general shooting. There are some limitations though. 


The sight can't handle recoil calibers of heavy-duty guns like the AK-47. Even though this scope would stay latched on to your AK without coming loose or coming apart, it would be irrelevant since the zero can't be sustained at all. However, the Truglo Tru-Brite can work for the weapons such as AR 10.5" pistols when co-witnessing it with a peep sight or something like an A2. 


Weighing a mere 5.4 ounces (0.33 pounds), this is surely one of the lightest scopes on the market. The featherweight, compact design does not negatively impact its rigidity and firmness. Although the coating sports some anti-reflection properties, it is not entirely anti-reflective.


The 3V CR2032 batteries aren't expensive and there's a wide variety of reticles to pick from, meaning that you'll be able to use this item for hunting aside from general-purpose shooting. To save battery power, it utilizes natural lighting for brightness control, which is a very smart use of the selective reflection.



  • Good for all-round shooting
  • Multiple reticles
  • Shock- and water-resistant
  • Parallax free from 30 yards
  • Very light
  • Very cheap



  • Not the best choice for precision shooting
  • Not suitable for rifle recoil like an AK
  • Aluminum screws come loose

A night vision mode allows you to co-witness this device with an iron or a peep sight by mounting it in front of an NV monocular. Those seeking a fast target acquisition will appreciate a quick-detach mounting system that comes with this sight as well as an internal locking system which ensures that the unit stays zeroed. That means you'll not have to readjust it frequently in the field.

Best Budget Red Dot Sights Buying Guide


An inexpensive yet good dot sight is the one that has several key features, such as sturdy mounting capability, a low weight, plenty of eye relief, and of course, a crystal clear view. It also must allow for fast target acquisition and quick shooting. Below, you can see some of the most important considerations and factors to look for when buying a red dot sight.


Weapon Mounting


Be sure that a mounting option for your red dot sight is reliable and solid. There are 2 most common rail mount types - Picatinny and Weaver. Most weapons come with either of these two rails so you should check the sight and your gun to see if they fit each other. If needed, you'll need to purchase a mount separately from the scope so as to suit both your weapon and sight.




Each red dot sight has a certain projection, either a holographic or reflex one. While the holographic sights create a red dot by means of a laser that projects the light on the viewing window, the reflex sights reflect the LED light in the line of shooting. The second type is 

more common and it consumes less battery life.


Minutes of Angle (MOA)


The MOA implies a dot size, i.e. a measurement consisting of a range of one inch per hundred yards. The greater the MOA, the more accurate your dot sight will be. While the bigger MOA is beneficial when shooting from far distances, it has no great significance for shorter distances.



Not every red dot sight is suited for every setup. Nonetheless, many dots are versatile and allow you to use them with a number of firearms, including pistols, rifles, crossbows, and shotguns. That's an important factor to take into account when picking the sight for your weapon.




This is a big deal when buying the red dot sight. DOA reticle, wandering zero, or flickering is just a waste of money. You should pick a dot that can hold up well. It also must be shockproof, fogproof, and waterproof.




Firearms aren't lightweight either. This especially applies to heavy handguns. So if you have a heavier big gun, adding a weighty dot sight will make you feel tired or uncomfortable after shooting a few rounds. This is why you should go for the lightweight sights.


Battery life


The battery lifespan varies from a few hundred to several thousand hours. Besides the lifespan, replacing the batteries could be a real issue in some models that require extra tools.


Wrapping Up


The optics empire seems to be massive with thousands of choices and a broad array of sighting systems. There's a wide variety of scopes, including those for close-range shooting, long-range shooting, and fixed power riflescopes. Yet, the red dot sights reign supreme in the realm of modern optics. 


Finding the best budget red dot could be a big challenge, though. This is especially true if you are seeking a cheap dot sight for rapid target acquisition in low light. Now that you're familiar with the top 10 picks for best budget red dot sights and tips on what to look for, it is much easier to make the right choice.
