Buying Guide For Red Dot Sights

When investing in a tactical red dot sight, you’ll want to do your research. Should you choose a cheap red dot sight or would it be best to invest in one that is a little more expensive? The truth of the matter is that there are tons of factors to take into consideration when attempting to choose one of these products. Below, you’ll learn more about the most important characteristics.

Brightness Settings

Whether you’re looking for a mini red dot sight or a conventional one, you’ll definitely want to consider the brightness settings. Most will provide you with a few settings at least. The brightness settings are very important because they’ll ensure that you’re able to see in pretty much any light condition. Try to find a scope that has at least three or four settings to choose from.

Battery Life

To ensure that you’re able to get the best red dot sight, you’ll need to make sure that it is going to be cost-efficient over a period of time. This is why battery life is so important. If you’re required to charge the battery after every other use, you’re going to be spending a lot over a period of time. Therefore, you should choose a sight that has a very long battery life.

Scratch Resistance

It is pertinent to choose a sight that is going to last a lifetime. Some are fragile and their lenses can be scratched very easily. This is something that you’ll want to avoid at all costs. Make sure that you choose a scope that has scratch-resistant lenses. This will ensure that your scope will withstand the test of time.

Water, Fog And Shock Proof

When reading red dot sight reviews, you’ll want to go above and beyond to ensure that the scope is protected from water, fog, and shock. You should never be afraid to spend more to ensure that these characteristics are present. After all, you’re going to encounter all types of weather conditions. You want to ensure that your scope is going to perform exceptionally well in all conditions. Water and fog proof can help. Plus, a waterproof scope is going to last much longer.

Shockproof is also important, due to recoil and drops.


Finding the best budget red dot can be much more difficult than you could ever imagine. Plus, you have to wonder whether or not the cheapest scope is going to be the best red dot sight for your individualistic needs. It is a good idea to set a budget before moving forward. This will ensure that you’re able to find the right scope for your budget. Spending as much as possible will usually ensure that you’re going to get the best scope for your money.


Some scopes are not going to withstand the test of time. They’re simply too fragile. A single drop might break them apart. This is why you need to choose a unit that is actually going to last. Make sure that you choose the material and the build. Be sure that the scope is made from the best materials humanly possible. Aircraft-grade materials will usually be your best bet.

Mount Type

You’ll also want to ensure that your scope will be compatible with your gun. Therefore, you’ll need to see if the scope works with Picatinny or Weaver rails. The good news is that some scopes are compatible with both. If you’re choosing a scope and don’t know much about them, it is best to choose a scope that will work with both types.


You just never know when something is going to go wrong. This is why you need to pay close attention to the scope’s warranty. It is nice to get a warranty for three or four years. However, you should realize that many scopes come with a lifetime warranty. If you want to ensure that your money is going to be spent well in the long run, you’ll definitely want to get a lifetime warranty!
