The AR-15 platform is one of the most versatile firearms available, and its adaptability extends to the slings that can be mounted on it. There is no single “best” sling for an AR-15—what works best depends on the user’s needs, how the rifle is set up, and how the sling is mounted. From simple carry straps to specialized tactical configurations, slings vary in design, attachment methods, and intended use.
Single-Point Slings
Single-point slings attach to the rifle at a single mounting location, typically at the rear of the lower receiver or near the endplate. These slings allow maximum freedom of movement, making it easy to switch shoulders and maneuver in tight spaces. They are often favored for close-quarters applications where a rifle needs to be kept readily accessible. However, because they do not stabilize the rifle against the body, they can allow excessive movement when not in use, leading to more fatigue over time.
Mounting Single-Point Slings
To attach a single-point sling, the AR-15 requires a suitable mounting point, usually achieved through one of the following:
- Endplate with a Sling Loop or QD Socket – Some endplates include a loop or a quick-detach (QD) socket for direct sling attachment.
- Receiver-Mounted Sling Plate – An aftermarket replacement plate between the receiver and buffer tube, offering an attachment point without modifying other components.
- Stock Attachment – Certain collapsible stocks feature built-in single-point sling mounts, eliminating the need for additional hardware.
While simple in design, single-point slings can result in the rifle bouncing around or swinging freely, which may be inconvenient for extended use.
Two-Point Slings
Two-point slings attach at two points on the rifle, usually at the front and rear. This setup provides better weight distribution and stability when carrying the rifle. Two-point slings are often preferred for general-purpose use, as they can be adjusted for comfort and provide better rifle retention.
Mounting Two-Point Slings
A two-point sling requires mounting points at both ends of the rifle. These can be attached in several ways:
- Fixed Stock Loops – Traditional rifle stocks often include built-in sling loops.
- Handguard Attachment Points – Many handguards, particularly free-float models, have dedicated sling attachment points.
- QD Mounts – Quick-detach mounts can be installed on both the stock and the handguard, allowing for easy sling removal and reconfiguration.
- Barrel Mounts – Some slings can attach directly to the barrel, typically using a clamping mechanism.
- Rail-Mounted Sling Adapters – For AR-15s with Picatinny, M-LOK, or KeyMod rails, adapters can be added to create front sling attachment points.
Two-point slings are often preferred for longer-duration carrying and provide more stability when shooting from a standing or supported position.
Three-Point Slings
Three-point slings have an additional loop that wraps around the shooter’s body, connecting to the rifle at two points. These slings offer greater retention and stability but can be more cumbersome than simpler options. They are less common today due to their complexity but are still used in certain applications where maximum rifle control is needed.
Mounting Three-Point Slings
Three-point slings typically attach using the same points as a two-point sling but include an additional strap that loops around the user’s body. This extra strap can be routed in different ways depending on user preference:
- Over the Shoulder – Common for patrol-style carry.
- Across the Chest – Keeps the rifle in a ready position while allowing hands-free movement.
- Fixed to Gear – Some configurations integrate with load-bearing vests or plate carriers.
While they provide excellent retention, three-point slings can interfere with rifle manipulation and are generally considered outdated compared to modern two-point or single-point designs.
Convertible Slings
Convertible slings offer the ability to switch between single-point and two-point configurations. These slings feature quick-adjustment mechanisms, allowing the user to detach or reconfigure the sling on the fly. This flexibility makes them a popular choice for users who need the advantages of both styles without committing to one or the other.
Mounting Convertible Slings
Convertible slings require multiple mounting points to function properly:
- Rear Mount for Single-Point Use – Typically a QD socket or a dedicated single-point loop.
- Front and Rear Mounts for Two-Point Use – Usually QD attachments, rail-mounted adapters, or built-in stock mounting points.
Some models allow conversion through the use of clips, buckles, or QD swivels, making the transition quick and easy.
Specialty Slings
Certain slings cater to specific applications beyond standard carrying methods. These include:
- Bungee Slings – Incorporate elastic sections for shock absorption, reducing strain when transitioning between ready positions.
- Precision Rifle Slings – Designed to assist in creating a stable shooting position by locking the rifle into the shooter’s body.
- Sniper and Marksman Slings – Often feature arm loops or tensioning mechanisms for added stability in prone or supported shooting positions.
Mounting Methods and Attachments
Regardless of the sling type, the method of attachment significantly affects usability. Some common mounting options include:
Quick-Detach (QD) Swivels
QD swivels allow for rapid removal and reattachment of the sling. They are widely used due to their reliability and ease of use. Many modern AR-15 stocks and handguards include built-in QD sockets.
HK-Style Hooks and Mash Hooks
These metal clips latch onto sling loops or rings on the rifle. They provide a secure attachment but can produce noise and wear on mounting points over time.
Paracord and Loop Adapters
For those looking for a minimalist approach, paracord loops or fabric straps can be used to create a sling attachment point without additional hardware.
Fixed Sling Loops
Some stocks and handguards include built-in loops that can accommodate standard slings without additional hardware.
Picatinny Rail Adapters
For rifles equipped with Picatinny rails, adapters can be installed to provide mounting points for various sling attachment methods.
Why Different Slings Suit Different Needs
Different slings serve different purposes based on how the rifle is used, the environment it will be carried in, and how quickly it needs to be brought into action. A two-point sling works well for general-purpose use, offering stability and comfort for extended carrying. It is commonly used in both civilian and professional settings because it provides good retention while still allowing quick access to the rifle.
A single-point sling allows for maximum mobility, making it useful in situations where quick transitions between shoulders or rapid deployment are necessary. However, it lacks support for hands-free retention, which can lead to excessive movement when the rifle is not in use.
A convertible sling offers the ability to switch between single-point and two-point configurations. This provides flexibility for those who need different capabilities based on their environment or role. Three-point slings, though less common today, offer more retention and control but can be cumbersome compared to other options.
Precision shooting slings provide additional stability by locking the rifle against the shooter’s body, making them ideal for long-range shooting or supported positions. The choice of sling depends on the balance between control, comfort, and speed of access, which varies based on the specific use case.
