Things to Consider Before Buying

No matter how helpful customer reviews and recommendations are, it is important to understand what you are getting into.

Here are some of the most important factors that must not be overlooked while choosing the best product as per your needs and requirements.

Types of Red Dot Sights

There are three main types of combat red dot sights available in the market. These types of red dot for hunting or other firearm activities include;

  • Reflex red dot sight
  • The prismatic red dot sight
  • The holographic red dot sight

Reflex red dot sight

This red dot sight works on a simple idea; utilization of glass and light. It has a spherical mirror that reflects the light that emits from an LED of axis focus. The special coating on the spherical reflector only allows red light to reflect through it. It is best for aiming without magnifying the target.

The prismatic red dot sight

Unlike traditional rifle scopes, prismatic red dot sight uses a glass prism to reflect the light that passes through the optics and folds it before reaching the eyepiece. These are a bit larger than reflex sights. The benefit of prismatic sight over others is that it offers a brighter and sharper image that gives a quicker target acquisition.

The holographic red dot sight

Holographic red dot sight uses mirrors and a laser to send a holograph back to you. This sight offers enhanced accuracy over other sights for firearms and also reduces the time to aim. Holographic sights provide unlimited eye relief, which gives you a greater situational awareness than other scopes.

Here comes a personal preference as choosing the one that suits your needs and requirements will only give you the best output.

Do not overlook the size

Where all of the sights works the same on a ground level, the size of the sight and the gun matters the most. For instance, where a handgun would work best with a smaller size, a rifle calls for larger sight. The bottom line is to perform well no matter what you go for but the size works the best for the weapon in question.

Battery Consideration

When we say battery, we count the life of a battery and also the ease of access. Just so you know, every product is not readily available in the market. There can only be one way to go for such kind of sights if it outweighs the performance and weapon compatibility, or else it is not worth the time, money, and effort.

Do not forget to look for the expected battery life on the box or in the specifications of the product before making a purchase.

Open vs Tube

Both the options come with their pros and cons, which leaves the decision solely on you. Buying the one that you are more comfortable and expert in using is the right thing to do. Open style offers unlimited scope but is more prone to damage.

Open styles sights use a small window, square-shaped. Whereas, tube style has all of the interior working parts of the optic encased inside a tube. Being enclosed in the tube, these optics offer a limited scope but are protected from wear and tear, giving a longer lifespan.

Reticle Size

Where most of the people think the size of the red dot does not matter, it does. The smaller reticle is ideal for precise shots at longer distances. Keep in mind that a smaller dot will automatically be harder to spot, especially if you are using it in the daylight. On the other hand, a way bit larger dot can hinder the sight of the target.

Here’s a little tip that can be of great help while choosing the reticle size; a general rule of thumb, inches versus yards. For instance, 1-inch red dot is ideal for aiming at hundred yards, a 2-inches diameter of the red dot is ideal for 200 yards, and so on.

Easy to go!

Keeping these factors in mind, you can never make the wrong decision while making a purchase for a red dot sight.

We see some of you are still not sure of what brand or the product they should go for or if it is the best product for the price.

Wait! We have got you covered with the best budget red dot sights that are the best in the market and are worth every penny.

Follow these easy three instructions to use a red dot sight: Step 1: Set up your target. Initially start with 25 yards as these are usually close range sights and not usually magnified. Step 2: Co-witness your scope. Look through your optic at your reticle and line it up directly on top of your iron post on the end of your barrel. Keep adjusting your dot vertically or horizontally till it lines up perfectly. Step 3: Aiming. Simply point and put the dot on your target.
A red dot sight is a common classification for a type of non-magnifying reflector sight for firearms that gives the user an aim point in the form of an illuminated red dot.
There is an LED light that shines directly onto the slightly angled glass that has special coating to show only the red light. These can also be green lights showing green dots.
