Best 3 Gun Scope From Expert Picks

The sport of 3-gun shooting is becoming quite well known. In 3-gun shooting you follow a course that requires you to use a different gun for each stage. A rifle, shotgun, and pistol are common. Typically, the targets are mid-range and close range with the occasional target at 500 yards.

This competition requires speed and accuracy. To help increase your skills, it is a good idea to use a scope. The challenge is to pick a scope that is flexible and allows you to mount and use it quickly.

Let’s take a look at Top 10 best scopes for 3-gun shooting.

Since 3-gun competition setups are constantly changing, you need to be prepared for any target. Some targets might be paper, others might be metal. You might even encounter clay pigeons. The point is, you have to be prepared for anything.

The scope you choose for 3-gun shooting needs to adapt to your range quickly. You might need to sight a target at a few yards or a couple hundred yards. You will not know until you begin the course.

The right scope will be versatile. It will allow you to sight at different distances. It will also be lightweight so that you won’t experience fatigue or need to re-zero your gun. You will be able to mount it quickly without effort.

The scoring of 3-gun shooting is based on accuracy and speed. Therefore, a good scope will help you score higher. Since you do not know what distance or targets you will encounter, you need to be prepared for anything. The best way to increase your accuracy score in a 3-gun shooting competition is to use a good scope.

Divisions of 3 Gun Shooting

Three-gun shooting can be broken down into five different divisions. You will be placed in a division depending on your skill level and your guns and accessories.

1. Limited

This is the beginner level. The equipment requirements for this division are the lightest, too. In Limited you can have one optic that’s unmagnified. It can be a red dot or iron sight. You can also not use a bipod. You cannot use optics on your shotgun either. However, the shotgun can be either semi-automatic or pump. The ammo must also be loaded by hand.

2. Tactical

The main difference between this division and Limited is that the optics on the rifle can be magnified. Most people prefer this division.

3. Heavy Metal / He Man

To compete in this category, your rifle must be 7.62 or larger. Your shotgun has to be a 12-gauge pump. You can only use iron sights for the rifle and shotgun. The handgun has to be a .45 ACP or larger. No optics are allowed with it.

4. Open

In this division your handgun magazine has to be 171.25mm or shorter. You can also use a speed loader for your handgun.

5. Outlaw Open

Anything goes in this division as long as it is safe.

Things to Consider Before Purchasing a Scope

When purchasing a scope for 3-gun shooting, you want to be sure it is versatile. It is also important to keep the following features in mind.

1. Magnification

Magnification is a definite must. You want to get a closer look at your target before you shoot. It makes a lot of sense to get a 3-gun scope that has great magnification levels. 

Ideally, the targets will be in both close and mid-range (specifically anywhere between 100 to 500 yards). So, the magnification levels should be anywhere from 1x to 8x.

2. Focal Plane

Most of the time, plane is a strictly personal preference. Just remember that with the first-focal plane, the reticle enlarges when you increase the magnification. When you use the second-focal plane, the reticle does not change.

3. Illumintaed Reticle

An illuminated reticle will really make a scope stand out. Such a reticle excels in a low-light environment while you are hunting. But if you are in competitions, it may also enhance your ability to hone on a target. Not to mention, illuminated reticles are not just useful in low-light settings. You can still use them during the day. They work especially well if it is rainy and the daylight is weak.

4. Eye Relief and Eye Box

eye relief

If you want to be able to see through the scope with both eyes, purchase a scope with an eye box and eye relief. You don’t want to make the mistake of looking too closely at the scope. You may get the dreaded scope eye. For a 3-gun Scope, you want to find a decent amount of eye relief. Remember, you still might be wrestling with some recoil if when using your new scope. Find a scope that allows you to see a great image in every head position.

Which is better for 3-gun shooting-first focal plane ( ffp ) or second focal plane ( sfp )? 

When it comes to 3-gun shooting competitions, most competitors prefer to use a scope with a second focal plane. This is because a first focal plane magnifies the image itself. When this happens, the image becomes harder to view. It might actually obscure some small long-range targets.

The second focal plane is preferred because it will be non-magnifying. This allows the user to view the targets without them being “hidden." You don't want magnification because 3-gun shooting involves hitting various targets at different distances quickly.

Which is better for 3-gun shooting - a scope or a red dot?

Since there are so many variables when it comes to 3-gun shooting, it is better to use a scope. The reason is simple. A good scope will allow you to adjust your settings for magnification and distance. A red dot can not be adjusted as easily. This makes the scope more useful in both mid-range and long range shooting.

The 3-Gun Competition

Now let’s take a closer look at 3 gun shooting competition. You will quickly see how the scope fits in.

A 3-gun shooting event has a set course at a range. You use 3 different guns throughout to attempt to hit various targets from different positions. The targets will be either close range and mid-range. You use a rifle, a pistol, and a shotgun. Your score is based on time minus penalties for missed targets. Each stage has assigned points that are based on the degree of difficulty. Simply put, the one who hits the most targets in the fastest time is the winner.

The AR 15 style rifle is the most popular choice for the rifle section. You definitely want to be sure that you purchase a decent 3-gun scope for your AR. The shotgun can be a pump-action gun. Actually, you should be aware that loading your shotgun on the timer is a big part of the competition. Be sure to always have extra shells with you.

As far as handguns, you will notice that many competitors prefer a 9mm. These are high-capacity guns, which is ideal when time is crucial. Be sure to bring at least 4 magazines and have belt-mounted magazine on hand. Typically 3 additional magazines are sufficient. You also should be sure that you have a 3-gun scope mount. The mount to be set up before beginning the course.

When putting together your 3-gun optics setup, you need to ensure that you have enough ammo to last you through the course. Accessories such as belts and pouches are also important. Once you begin, you need to be continue smoothly from one stage to the next.

And, of course, make sure you have the correct gun cases so that you can safely move from stage to stage. Having chamber flags on hand is great. They indicate when the guns are empty. Keep in mind, some ranges require the use of these flags.


3-gun shooting is rapidly gaining in popularity. It is an exciting sport that challenges you to quickly adapt to different targets, different distances, and different guns.

With planning, you can have the right equipment to be successful. Your score is based on how quickly and accurately you hit targets, so adding a scope can make all the difference.

Think about the guns you will be using and make sure that the scope you choose can be properly mounted. Then all you need to do is load up your equipment and head to the nearest course. Not sure where to do some 3-gun shooting? Ask at your local gun shop. You’ll be glad you did.
