Choosing the Right Scope

When choosing a scope for your AR-15, there are a few things you need to consider.

  • The type of shooting you will be doing. If you plan on doing mostly long-range shooting, you will need a scope with a higher magnification. If you will be doing more close-range shooting, you can get away with a lower magnification scope.
  • The size of your AR-15. The size of your AR-15 will determine the size of the scope you can use. If you have a small AR-15, you will need a smaller scope.
  • Your budget. Scopes can range in price from a few hundred dollars to several thousand dollars. You need to decide how much you are willing to spend on a scope.

Here are some of the different types of scopes that are available for AR-15s:

  • Magnification scopes: These scopes have a magnification range of 1x to 10x. They are ideal for long-range shooting.
  • Red dot sights: These scopes have a red dot in the center of the lens. They are quick to acquire targets and are ideal for close-range shooting.
  • Holographic sights: These scopes project a holographic image of the reticle onto the lens. They are very fast to acquire targets and are ideal for close-range shooting.

What features should you look for in a scope?

When choosing a scope for your AR-15, there are a few features you should look for.

  • Magnification: The magnification of a scope is the amount of times it makes the image appear larger. Scopes for AR-15s typically have a magnification range of 1x to 10x. For long-range shooting, you will need a scope with a higher magnification. For close-range shooting, you can get away with a lower magnification scope.
  • Objective lens diameter: The objective lens diameter is the diameter of the lens at the front of the scope. The larger the objective lens diameter, the more light the scope will gather. This can be beneficial in low-light conditions.
  • Eye relief: Eye relief is the distance between your eye and the scope’s ocular lens. If the eye relief is too short, you will have to put your eye too close to the scope, which can be uncomfortable and can lead to eye fatigue. If the eye relief is too long, you will have to focus your eyes through the scope, which can be difficult.
  • Field of view: The field of view is the amount of area you can see through the scope. A wider field of view is better for close-range shooting, while a narrower field of view is better for long-range shooting.
  • Reticle: The reticle is the crosshairs or other aiming point in the center of the scope. There are many different types of reticles available. Some reticles are designed for specific types of shooting.
  • Parallax adjustment: Parallax adjustment is a feature that allows you to compensate for the parallax error. Parallax error is the difference in the point of impact between the reticle and the target when the shooter’s head is not perfectly aligned with the bore of the rifle.

How to mount a scope on your AR-15

To mount a scope on your AR-15, you will need a few tools:

  • A scope mount
  • A torque wrench
  • A set of Allen wrenches

3. Using Your Scope

Once you have sighted in your AR-15, you can start using your scope to make accurate shots. Here are a few tips for using your scope effectively:

  • Hold your AR-15 firmly while aiming. Your body should be relaxed, but your grip on the rifle should be firm. You should be able to control the recoil without your aim shifting.
  • Look through the scope with both eyes open. This will help you to maintain your peripheral vision and stay aware of your surroundings.
  • Focus on the target. Don’t let your eyes wander. Keep your focus on the target until you have made the shot.
  • Squeeze the trigger slowly and smoothly. Don’t jerk the trigger or you will likely miss your target.

Here are some additional tips for using your scope to make accurate shots:

  • Practice regularly. The more you practice, the better you will become at using your scope.
  • Vary your shooting positions. Practice shooting from different positions, such as standing, kneeling, and prone. This will help you to become comfortable shooting from any position.
  • Use different types of ammunition. Experiment with different types of ammunition to find the one that works best for your rifle and your shooting style.

4. Troubleshooting

If your scope is not zeroed, or if it becomes blurry or damaged, you will need to troubleshoot the problem. Here are a few things you can check:

  • Make sure the scope is mounted correctly. The scope should be mounted securely to the rifle so that it does not move when you fire the rifle.
  • Check the scope’s adjustments. The scope may be out of adjustment if you have not used it in a while, or if you have dropped the rifle.
  • Clean the scope’s lenses. If the lenses are dirty, they may be blurry. Use a soft cloth to clean the lenses.
  • Replace the scope’s batteries. If the scope is powered by batteries, they may be dead. Replace the batteries and see if the problem is resolved.

If you have checked all of these things and the problem persists, you may need to take the scope to a qualified gunsmith for repair.

Sighting in your AR-15 and using your scope effectively takes practice. However, with a little time and effort, you can become a proficient shooter. By following the tips in this guide, you can learn how to sight in your AR-15 and use your scope to make accurate shots.

How To Sight In An Ar 15?

  • What is the best way to sight in an AR-15? There are a few different ways to sight in an AR-15, but the most common method is to use a 25-yard zero. To do this, you will need a target that is at least 25 yards away, a shooting rest, and a few rounds of ammunition.
  • How do I use a 25-yard zero? To use a 25-yard zero, you will first need to set your rifle’s sights to the factory default setting. This is usually a 1-inch group at 100 yards. Once your sights are set, you will need to fire three rounds at the target, aiming for the center of the bullseye. If your rounds are grouped together, you can adjust your sights as needed.
  • What if my rounds are not grouped together? If your rounds are not grouped together, you will need to adjust your sights. To do this, you will need to turn the windage and elevation knobs on your rifle’s sights. The windage knob controls how far left or right your rounds will hit, and the elevation knob controls how high or low your rounds will hit.
  • How do I know how much to adjust my sights? To determine how much to adjust your sights, you will need to measure the distance between the center of your group and the bullseye. Once you have this measurement, you can use the following formula to calculate how much to adjust your sights:

Adjustment = (Distance between group and bullseye) / (Distance to target)

For example, if your group is 2 inches from the bullseye and you are shooting at a target that is 25 yards away, you would need to adjust your sights by 0.08 inches.

  • What are the other ways to sight in an AR-15? There are a few other ways to sight in an AR-15, but the 25-yard zero is the most common method. Other methods include using a 100-yard zero, a 300-yard zero, or a Kentucky windage.
  • What is a 100-yard zero? A 100-yard zero is when your rifle is sighted in so that the point of impact is 1 inch high at 100 yards. This is a good option for hunters who are shooting at targets that are within 100 yards.
  • What is a 300-yard zero? A 300-yard zero is when your rifle is sighted in so that the point of impact is 2 inches high at 300 yards. This is a good option for long-range shooters who are shooting at targets that are beyond 300 yards.
  • What is Kentucky windage? Kentucky windage is a method of adjusting your sights to compensate for wind. To do this, you will need to estimate the wind speed and direction, and then adjust your sights accordingly.

Additional Tips for Sighting In an AR-15

  • When sighting in your AR-15, make sure to use a good quality target. A target that is too small or too blurry will make it difficult to see your group and make adjustments.
  • Make sure to use the same type of ammunition when sighting in your AR-15. Different types of ammunition can have different ballistics, so using the same type of ammunition will help to ensure that your rounds are grouped together.
  • Be patient when sighting in your AR-15. It may take a few tries to get your sights dialed in, but it is worth it in the long run.
  • If you are having trouble sighting in your AR-15, you can always take it to a gunsmith. A gunsmith can help you to get your sights dialed in so that you can hit your targets with confidence.

Sighting in an AR-15 is a relatively simple process, but it is important to follow the steps carefully in order to get your sights dialed in correctly. By following the tips in this guide, you can be sure that your AR-15 will be accurate and reliable.
