Things to Consider Before Buying

There are many sighting devices, but none can compare to the parallax free dot sights. They increase shooting precision and accuracy to a great percentage. Mostly, where the dot points, that is where the shot goes. In order to get sights which will serve you well, put the following points into consideration in your selection process.

Holographic or Red Dot Sight

A red dot sight is the one that makes a mark on the target object surface, and it can sense, or any third party can see that something is going on. These kinds of sights are not the best for military operations or law enforcement tasks.

Holographic Red Dot Sight

A holographic dot sight is the option to consider under these conditions since it does not create awareness on the environment that a particular object is being targeted. Only the shooter can see the dot from the tube though it appears to be on the target’s body.

Red Dot Size and Color

Most of the dot sights are either red, green or have both colors. Each color is optimized for use in different prevailing conditions. Red is suitable for use at night and green is preferred during the day. However, depending on the brightness level of the dots any of them can be used on either day or night.

If you are most active during the day, you can opt to look for a red dot sight that is not easily neutralized by natural light or just go with the green dot sight. Dot size ranges from 1 to 5 for most of the red dot sight devices.

Red Dot Sight Reticle

The dot size is measured in MOA on a 100 yardage. Thus a 1 MOA dot is one inch on the target at 100 yards. Due to this, the larger the dot size, the lesser the gadget is suited for long-range shooting. For example, a 5 MOA dot on a target that is 300 yards away would cover majority parts of the target.

Water and Fog Resistant

Majority of the gun users do their activities outdoor. The prevailing environmental conditions in the outdoor can be harsh or favorable, and your red dot sight should perform well in both situations.

The main two things that hinder the performance of a rifle in the outdoors are rain and fog. Rainwater can cause the device to shut down while fog makes the lenses almost impossible to see through them.

To curb these challenges majority of the manufacturers are willing to purge their gadgets with nitrogen to make them fog resistant as well as using single chassis construction system. Any opening joint is also fitted with rubber bands to keep them water and moisture resistant.


It is the single element that determines whether all the sights which have passed all the other tests as outlined above will end in your cart. If you cannot meet the cost; all the other elements of a red dot sight will not be of much significance to you. If you choose to buy a lowly priced red dot sight, you might be required to put up with some minor flaws though not always. Highly priced items are in most of the times well built and checked thoroughly for any minor flaws.


A hunting rifle can have too many accessories attached to it for a successful hunting mission. Some may have scopes, magnifiers, iron sights, and the dot sights.

To reduce the bulkiness on your weapon, you should consider and prefer to use lightweight items, and this is not exceptional to the parallax free red dot sights. The lighter your rifle is, the easier it will be to use in the field.
