best 3 gun scope

3 gun competitions are becoming more and more popular. They require a lot of speed, accuracy, and efficiency. 3 gun competitions involve using three different guns at different stages with varying targets and distances.

Finding the best 3 gun scope will help you perform your best during these competitions. We’ve created a list of the top scopes for 3 gun competitions to help make sure you have the perfect equipment to help you succeed.

What you need to consider before purchase 

Before you decide on a 3 gun scope there are certain things you’ll need to consider. Because 3 gun competitions have a lot of variety, you need a scope that will be flexible and work well in all kinds of situations.


3 gun competitions involve mid-range and close-range targets, sometimes at a distance of up to 500 yards. Because of that, you’ll need a scope with an adjustable magnification range.

You need to be prepared for anything because you never know what the course layout will be like. Most 3 gun shooters choose scopes with low-power magnification because high magnification can be distorting when trying to shoot fast.

Usually, the best scope to go with has a 1X magnification, which causes no distortion and no actual magnification. Looking through the scope should be identical to looking with plain eyes. Having a scope that is adjustable between 1-8X scope is ideal because it will allow you to see close targets normally and magnify targets that are farther away.

Focal Plane

Deciding between first-focal-plane and second-focal-plane may be a personal choice but there are a few things to keep in mind. With first-focal-plane, the reticle becomes enlarged as you increase magnification. 

With second-focal-plane however, the reticle stays the same size at all magnifications. Most long-distance shooters prefer first-focal-plane scopes but many 3 gun competitors complain that the reticle covers too much of the target when magnified. So most of them choose second-focal-plane scopes.

Illuminated Reticle

Having an illuminated dot aid at the center of your scope can be very helpful during 3 gun competitions. It helps to draw your eye to the center and is easy to see in any light condition. Having this aid will help you shoot more accurately and quickly.

Also, illuminated reticles help you clearly see the target in all kinds of lighting situations. Whether you’re shooting in dark or daytime conditions, you want to make sure you can see every target clearly during the competition.

Eye Box & Eye Relief

The eye box refers to the space that you can move your head around and still see through the scope. Some scopes require you to be perfectly aligned with the center of the lens to be able to see through it.

This can slow you down during a 3 gun competition where you don’t always have the time to line up perfectly before making the shot. Having a larger eye box will allow you to see through the scope quickly and at different angles to help you get the perfect shot faster.

Along with the eye box, you'll want to consider eye relief as well. This is the distance that your eye has to be from the lens for you to be able to see a full image through the scope. If your scope has a short eye relief, you'll have to be very close to the lens to see anything.

However, with a longer eye relief, you can easily see through the lens at a further distance. This is helpful because you can start to see your target sooner when you look through the lens. This will help you find and shoot your target quicker and more accurately, which will help immensely in a 3 gun competition.
