Whether you are someone who has bought his first rifle or a seasoned professional marksman with a rich arsenal of weapons, the budget is something that always matters. Tactical rifles are kind of like Legos as their cost tends to rapidly add up. This is why you should be very careful with your purchase.

Why are red dots so popular? That’s because they allow for more accurate rapid fire and quicker reaction than any iron sight. These ultra modern optics are designed specifically to provide users with unlimited eye relief and more intuitive shooting experience than traditional sights.

Besides, red dots are fairly easy to use and don’t take a lot of training to get mastered. On the top of that, red dot scopes work perfectly on just about any weapon platform, which is why many people like to use them.

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.

The people who enter your home most likely do not have training on how to handle or use a weapon. They might become curious when they see a gun lying somewhere in your house, holding it and checking it. This is when accidents happen.

Such kind of situation will not happen if your gun is safely stored in your locked gun safe.


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.
