Red Dot Buying Guide

A red dot sight needs to be adjusted in the same manner as a regular scope. It has elevation and windage adjustments.

There are various things I would urge you to consider when shopping for a red dot, including:

Dot Size

The dot can come in different sizes, and it is usually measured in minute of angle (MOA). You can choose a small or large dot, depending on your application.

A larger dot size is more useful on firearms that will be engaging close range targets. A smaller dot size is suitable for more precise shot placement.

Tube or Open Design

Tube or closed red dot sights provide you with the ability to add filters and fitted dust covers for protecting the optics from the elements and damage.

An open style red dot doesn’t have a tube, but you can find the optics situated in front of the emitter. This design is normally lightweight and compact.

Rifle Scope Buying Guide

Scope selection requires you to pay close attention to specific design features, even though there are so many things to consider.

Durable Construction

You want the best investment that will last a long time. So, you have to choose a scope that is either nitrogen or argon purged for weatherproofing.

A durable scope should also be O-ring sealed, this will ensure no water of any kind or debris gets into the scope internal mechanism.

Magnification

There are two types of magnification: fixed and variable. I will urge you to consider the latter because it is more versatile, depending on your application.

Elevation and Windage Adjustments

Elevation and windage adjustments are extremely important because they determine how accurate your scope will be.

To get the best adjustments, you have to choose high performing turrets. One of the most popular designs is ballistic turrets.

Scope vs Red Dot Sight — Which is the Better Option?

The red dot vs scope battle is fierce, but I am going to breakdown the comparison into a few categories to determine the overall winner.

Category One: Speed

The advantage here has to go to the red dot sights because they are simply engineered for speed. They have a very simple and visible reticle and they don’t have magnification.

On the other hand, scopes tend to be a little bit slower because they require eye relief and magnification. Both require time to get used to.

Category Two: Accuracy

The advantage here goes to the scope. This is so since accuracy requires magnification in order to see fine details. Red dots don’t have magnification.

Category Three: Weight

By design, red dots are lighter in weight. So, they are more convenient when you want to shave off a few ounces from your rifle.

Category Four: Reliability

The advantage here goes to the scope, simply because the reticle of the scope does not rely on batteries. In some cases, the batteries may go dead or fail.

Final Words

A red dot is faster because it does not depend on magnification when acquiring the target position. It simply points to the target.

A red dot is also extremely lightweight, especially the compact open design. They are perfect when you want to reduce the weight of your rifle.

A scope; however, is more accurate because it uses magnification and high performing reticle designs for image acquisition. Also, scopes are more reliable because they don’t depend entirely on batteries.

Based on our findings, our overall best red dot sight is the Sig Sauer Romeo5 and the best overall scope is the Nikon Buckmasters II.
