How Accurate is an AR-15?

Is America’s favorite rifle also the most accurate?

The AR-15 styled rifle is often dubbed as “America’s Favorite Rifle”, renowned for its versatility, modularity, and ability to be customized with all different types of attachments, from different handguards to muzzle devices such as suppressors. Being created by Eugene Stoner who also created the infamous M16, the civilian AR-15 has evolved into a platform used for everything from sport shooting to hunting to home defense. But, how accurate are these AR-15 rifles?

Let’s take a deeper look into AR-15s, and the accuracy that can be associated with them.

Understanding the factors that contribute to its accuracy and the role of sighting systems can help shooters maximize their performance with this iconic firearm.

Factors Influencing AR-15 Accuracy

Barrel Quality

The barrel is a critical component that significantly affects accuracy. High-quality barrels made from premium materials and with precise rifling can produce tighter groupings. The length of the barrel also plays a role; longer barrels tend to offer better accuracy at longer ranges due to increased bullet velocity and stability, while shorter barrels are better for maneuvering in close quarters combat scenarios. That being said, a longer barrel can also make the rifle less maneuverable, which is a consideration for close-quarters situations.

Ammunition

The type of ammunition used can greatly impact accuracy. The AR-15 is chambered in various calibers, with the .223 Remington and 5.56 NATO being the most common. Match-grade ammunition, which is manufactured to stricter tolerances, can enhance accuracy. Consistency in the weight and shape of the bullets, as well as the amount of propellant, contribute to more predictable performance. It's also important to regularly clean the rifle and maintain it to ensure that the ammunition performs at its best.

Trigger Mechanism

A crisp, clean-breaking trigger allows for better control during firing. Aftermarket triggers can be installed to replace standard mil-spec triggers, providing a lighter pull weight and reducing trigger creep, which can lead to more precise shooting. A two-stage trigger, which has a light initial take-up followed by a crisper break, can further enhance accuracy by giving the shooter better control over when the shot breaks.

Shooter Skill

The skill and experience of the shooter cannot be underestimated. Proper shooting techniques, including breath control, trigger discipline, and a stable shooting position, are essential for achieving maximum accuracy. Regular practice and training are vital, as they help the shooter become more familiar with the rifle and improve their ability to make accurate shots. Participation in shooting competitions or training courses can also provide valuable experience and feedback.

Accessories and Customization

The modular nature of the AR-15 allows for extensive customization, which can impact accuracy. Free-floating handguards, which do not contact the barrel, can prevent interference that could affect the barrel's harmonics and, consequently, accuracy. High-quality optics and iron sights, muzzle devices like compensators or flash hiders, and even the choice of stock can all influence how well the rifle performs.

You can also opt for something like a rifle sling and pair it with the sling tab, a device from Core Vision Training that allows for a shooter to take their shots more accurately when firing from cover.

Iron Sights vs. Optics on an AR-15

Iron Sights

Iron sights are the most basic and traditional aiming devices for rifles. They consist of a front sight post and a rear sight aperture. Iron sights are durable, require no batteries, and can be very accurate at close to medium ranges with proper training. 

However, they can be challenging to use for precision shooting at longer distances and in low-light conditions (unless you are wearing night vision goggles of course). Aligning the front and rear sights while focusing on the target can be more difficult and time-consuming than using an optic.

Optics

Optics, including red dot sights and scopes, offer significant advantages over iron sights in many scenarios.

Recommended Optic for Close to Medium Range: Trijicon RM06 RMR Type 2

Red dot sights provide a single point of aim with a bright reticle, allowing for rapid target acquisition. They are ideal for close to medium-range shooting and excel in dynamic situations where speed is crucial. The Trijicon RM06 RMR Type 2 is a prime example of a high-quality red dot sight suitable for the AR-15.

The Trijicon RM06 RMR Type 2 Adjustable LED Reflex Sight is a top-tier choice for those looking to enhance their AR-15's performance at close to medium ranges. This optic features a 3.25 MOA red dot reticle, providing a brilliant aiming point that is easy to pick up quickly. Key features include:

  • Rugged Construction: Engineered with 7075-T6 aluminum housing, this sight is built to withstand harsh conditions, including impacts and submersion up to 66 feet.

  • Adjustable LED Illumination: Users can switch between automatic brightness control and eight manual settings, including options for night vision devices and a super-bright setting for daylight use.

  • True-Color Multicoatings: These coatings ensure that targets and backgrounds are seen without color distortions, providing a clear and accurate sight picture.

  • Parallax-Free: The sight offers parallax-free performance, ensuring that the point of aim remains true regardless of the angle of view.

  • Wide Adjustment Range: With 150 MOA for both windage and elevation and 1.0 MOA clicks for impact point correction, it provides ample adjustment for precise shooting.

The RM06 RMR Type 2 is user-friendly, featuring improved electronics and battery contacts for reliable performance. Its compact size and durability make it suitable for use on rifles, pistols, or shotguns. The battery conservation mode and button lockout features help maintain optimal performance and prevent accidental adjustments. Its compact design does not add significant weight or bulk to the rifle, making it ideal for dynamic shooting scenarios.

Recommended Optic for Medium to Longer Range: Trijicon Credo MRAD 1-8x28 FFP

Scopes offer magnification, which is essential for long-range precision shooting. They come in various configurations, from low-power variable optics (LPVOs) to high-powered scopes. The ability to zoom in on distant targets can significantly improve accuracy at longer ranges. Scopes with first focal plane (FFP) reticles, which scale with the magnification, are particularly useful for range estimation and holdovers.

For shooters seeking versatility in medium to long-range engagements, the Trijicon Credo MRAD 1-8x28 FFP is an exceptional choice. This riflescope combines the benefits of a red dot sight for close quarters with the precision of a scope for longer distances. Key features include:

  • Magnification: The 1-8x magnification range allows for quick target acquisition at 1x and precise shot placement at higher magnifications.

  • Illuminated Reticle: The dual red/green illuminated MRAD Segmented Circle reticle is designed for both CQB and distance shooting, ensuring visibility in any lighting condition.

  • Superior Glass Quality: Fully multi-coated, broadband, anti-reflective glass provides a clear and bright sight picture, enhancing target acquisition and identification.

  • Durable Construction: The 34mm tube and 28mm objective lens are built to withstand rugged use, offering reliability and performance in the field.

  • First Focal Plane (FFP) Reticle: The FFP reticle ensures that the scale of the reticle remains constant relative to the target, providing accurate holdovers and range estimation at any magnification level.

The Credo 1-8x28 is favored by competitive shooters and tactical users for its robust performance and flexibility. Whether engaging targets at close range or dialing in for a long shot, this optic delivers consistent accuracy and durability. Its low-light performance and rugged construction make it suitable for a variety of shooting environments and conditions. The generous exit pupil and clear glass ensure that the shooter can maintain a full field of view and situational awareness.
