Choosing the Right Scope

The first step in zeroing your AR-15 is choosing the right scope. There are a few things to consider when choosing a scope, including:

• Your budget: Scopes can range in price from a few hundred dollars to several thousand dollars. It’s important to set a budget before you start shopping so you can narrow down your options.
• Your intended use: Will you be using your AR-15 for hunting, target shooting, or self-defense? The intended use of your rifle will help determine the features you need in a scope.
• Your shooting skills: If you’re a beginner shooter, you may want to choose a scope with a lower magnification and a wider field of view. This will make it easier to track your target and make accurate shots.

Once you’ve considered these factors, you can start narrowing down your choices. Here are a few things to look for in a good AR-15 scope:

• Clear glass: The most important factor in a good scope is the clarity of the glass. You want a scope that will give you a sharp, clear image of your target, even at long distances.
• Adjustable magnification: A variable-power scope allows you to adjust the magnification, which is helpful for different shooting situations. For example, you may want a higher magnification for target shooting, and a lower magnification for hunting.
• Waterproof and fog-proof: If you plan on shooting in wet or humid conditions, you’ll want a scope that is waterproof and fog-proof. This will help to prevent the scope from fogging up or getting damaged by water.
• Reticle options: There are a variety of reticles available for scopes, each with its own advantages and disadvantages. Some common reticles include the crosshair, the dot, and the mil-dot. You’ll need to choose a reticle that works well for your intended use.

Here are a few specific scopes that are well-suited for AR-15s:

• Vortex Optics Crossfire II 2-7x32mm Riflescope: This is a great option for beginner shooters or those on a budget. It has a clear glass, a variable magnification range of 2-7x, and is waterproof and fog-proof.
• Leupold Mark AR MOD 1 3-9x40mm Riflescope: This is a more expensive option, but it offers excellent performance. It has a clear glass, a variable magnification range of 3-9x, and is waterproof, fog-proof, and shockproof.
• Primary Arms SLx 1-6x24mm Riflescope: This is a good option for shooters who want a scope with a wide field of view. It has a variable magnification range of 1-6x, a clear glass, and is waterproof and fog-proof.

Mounting a Scope on Your AR-15

Once you’ve chosen a scope, you’ll need to mount it on your AR-15. There are a few different ways to mount a scope, but the most common method is to use a scope mount. Scope mounts come in a variety of styles, so you’ll need to choose one that is compatible with your rifle and scope.

To mount a scope, you’ll need to:

1. Remove the factory iron sights from your rifle.
2. Install the scope rings on your rifle.
3. Mount the scope on the scope rings.

Here are some tips for mounting a scope:

• Make sure the scope rings are properly aligned with the bore of your rifle.
• Tighten the scope rings securely, but don’t overtighten them.
• Test the scope by sighting it in at a target.

Zeroing Your Scope

Once you’ve mounted your scope, you’ll need to zero it. Zeroing your scope means adjusting the sights so that the point of impact of the bullet matches the point of aim. This will ensure that your shots are accurate.

To zero your scope, you’ll need to:

1. Find a suitable target.
2. Set up your rifle at a comfortable shooting position.
3. Load your rifle with ammunition.
4. Aim at the target and fire a shot.
5. Adjust the scope sights until the point of impact of the bullet matches the point of aim.
6. Repeat steps 4 and 5 until your scope is zeroed.

Here are some tips for zeroing your scope:

• Start with a low magnification setting.
• Make small adjustments to the scope sights.
• Take your time and be patient.

Once your scope is zeroed, you can enjoy accurate shooting with your AR-15.

3. Maintaining Your Scope

How do I zero an AR-15?

1. Choose the right ammunition. The type of ammunition you use will affect the point of impact (POI) of your rifle. Make sure to use the same type of ammunition that you will be using for target shooting or hunting.
2. Find a safe and clear shooting range. Make sure that the range is large enough to accommodate the distance you will be zeroing your rifle at.
3. Set up your rifle. Attach a scope or red dot sight to your rifle and mount it securely. Make sure that the scope is properly aligned with the bore of your rifle.
4. Establish a zeroing target. The target should be at a known distance, such as 25 yards or 100 yards. The target should be large enough to see clearly, and it should have a consistent aiming point, such as a black dot or a bull’s-eye.
5. Zero your rifle. Fire three shots at the target, aiming at the center of the aiming point. If the shots are grouped together, you have successfully zeroed your rifle. If the shots are not grouped together, adjust the scope or red dot sight until the shots are grouped together.
6. Test your zero. Fire three more shots at the target to make sure that the zero is still accurate. If the shots are still grouped together, your rifle is now zeroed.

What are the different types of AR-15 sights?

There are three main types of AR-15 sights: iron sights, scopes, and red dot sights.

• Iron sights are the most basic type of AR-15 sight. They consist of a front sight post and a rear sight aperture. Iron sights are simple to use and relatively inexpensive, but they are not as accurate as scopes or red dot sights.
• Scopes are telescopic sights that magnify the target. Scopes are more accurate than iron sights, but they are also more expensive and more difficult to use.
• Red dot sights are electronic sights that project a red dot onto the target. Red dot sights are very easy to use and very accurate, but they are also more expensive than iron sights.

What is the best type of AR-15 sight for me?

The best type of AR-15 sight for you depends on your needs and budget. If you are looking for a simple and inexpensive sight, iron sights are a good option. If you are looking for a more accurate sight, a scope is a good option. If you are looking for a very easy-to-use sight, a red dot sight is a good option.

**How do I adjust the sights on my AR-15?

To adjust the sights on your AR-15, you will need a screwdriver or Allen wrench.

1. Locate the adjustment screws on your scope or red dot sight. The adjustment screws are usually located on the side or top of the sight.
2. Turn the adjustment screws in the direction that you want to move the POI. To move the POI up, turn the adjustment screws clockwise. To move the POI down, turn the adjustment screws counterclockwise.
3. Fire three shots at the target and check the POI. If the POI is not where you want it, adjust the sights again and fire three more shots. Repeat this process until the POI is where you want it.

What is the difference between a front sight post and a rear sight aperture?

The front sight post is a vertical post that is located at the front of the rifle. The rear sight aperture is a small hole or slot that is located at the rear of the rifle. The front sight post and the rear sight aperture work together to create a sight picture that allows you to aim your rifle at the target.

**What is the best way to hold an AR-15?

The best way to hold an AR-15 is with a firm grip on the pistol grip and the support hand on the foregrip. Your dominant eye should be aligned with the scope or red dot sight.

**What are the most common mistakes people make when zeroing an AR-15?

The most common mistakes people make when zeroing an AR-15 are:

• Using the wrong ammunition
• Not using a consistent aiming point
• Not adjusting the sights correctly
