Best Red Dot Sight Under 100 - Buying Guide

Things to Consider When Choosing the  Best Red Dot Sight

The fact that you are shopping for low cost red dot sight doesn’t mean that all the models on the market will meet your requirements. The last thing that any hunter needs is an optic that will cause more disappointments. To help you pick a quality product, I have prepared a buying guide to help you know some of the most important things that you should consider before you buy the best red dot sight under 100.

Dot Size

When searching for red dot sight, you will find many models with different minute of angle (MOA). This is the size of the dot which you should take into account when buying. For most sights, you will find that they have an average MOA of around 4. You can also find other that have MOA of up to 60. If you want to view your target well, look for a red dot sight with an MOA that is not too small or too big.

Construction

Buying low-priced optics doesn’t mean that you should compromise on the quality. Look for a product that features a strong construction and made with durable materials so that you can enjoy a great performance for many years. On top of that, make sure that you pick a lightweight product which will be easy to carry when you are going for a hunting trip.

Battery Life

This is another important thing that you should check when buying red dot optics. If you want your hunting experience to be better, look for a sight that will provide you with longer battery life. You don’t want a sight with a low battery life that forces you to stop what you are doing to change the battery.

Water/Fop Proof Design

Sometimes, you might be hunting in extreme weather conditions. If your sight is not water or fog proof, this means that its performance will be affected if you use it under such conditions. Look for a red dot sight with a waterproof and fog proof design so that you can enjoy a great performance even when the weather is extreme.

Variable Brightness

Yet in other times, you might find yourself hunting in low light conditions. In such cases, you can appreciate having a sight with a variable brightness. This will help you set the right brightness for use in low light conditions.

Projection type

When it comes to the type of projection, you can either choose a holographic or the best reflex sight. In holographic projection, sight illumination comes from the front of the lens and the laser diode light is projected to the viewing window to come up with a red dot that will help you aim your targets. In reflex sight, an LED light is reflected behind the lens of your sightline.

Style of Reticle

Reticles come in different styles and they are illuminated to make your work easier when you are shooting in low light conditions. You will find that the color and the pattern of the red dot vary so you need to look for the best that will make shooting comfortable. When it comes to style, you can get single dot, cross hairs and bullseye patterns that can be displayed in either green or red color. You can also adjust the size of the reticle. Having a bigger dot means that your targeting will be easier.

Size and weight

You should also consider the size and weight of the red dot sight before you purchase. Make sure that you get the right size that suits your gun and will be easy to store. If the red dot sight you choose is heavy, it will also affect the overall weight of your gun. To get accuracy when shooting, ensure that you can still handle the gun effectively even when the sight is attached.

Gun compatibility

Red dot sights are designed differently meaning that they are not compatible with all guns. Different sights are made for certain types of guns to perform well. Ensure that you buy a sight that is compatible with your gun so that you can enjoy using it. Additionally, you should know how to shoot with a red dot sight well so that you can get acute shots all the time.

Mounting

Whether you choose the vortex optics Sparc ii 2 moa red dot sight, or any other ideal sight you decide to buy, you need to consider how you will mount it. This is important because if your sight is slightly off, then your aiming will be off as well. Mount and adjust the scope well and ensure that it is straight. Proper mounting will help you achieve precision and this helps you to aim at your targets well.

Advantages of Using Red Dot Sight

If you would like to improve your hunting techniques, buying the best red dot sight under 100 can be a great addition. There are so many benefits that you will get when you mount a red dot on your gun. First, you will achieve fast target acquisition.
