The 3 Best AR-15 Sling [2021 Update]

Today I’m going to show you the best AR-15 sling on the market today.

In fact:

I’ve hand-tested over 10 AR-15 slings alone for this review.

The best part?

I’ve sorted them by use. So whether you’re on a budget or looking for the most premium sling, you’ll find it here.

Let’s get started!

The 3 Best AR-15 Sling

If you’re pressed on time, here’s a quick list of the best AR-15 sling:

  1. S2 Delta: Best Sling for AR-15
  2. Tactical Hero Rifle Sling: Best Tactical Sling
  3. STI 2 Point Rifle Sling: Best Two-Point Sling

1. S2 Delta: Best Sling for AR-15

Not only can a great sling make it more comfortable to carry your weapon for longer periods of time, it can also give you the stabilizing power you need to improve accuracy.

The comfort, convenience, and quality build of the S2 Delta sling does both of these things and more.

That’s why I’ve chosen it as the best AR sling.

Let’s dive into the features of this exceptional sling…


Built with durable woven mil-spec webbing the S2 Delta sling is made to last under the harshest conditions.

This newer company is veteran-owned and operated, and they’ve committed to using only the highest quality USA-made components in their products.

When I first pulled my new sling out of the package, I was immediately impressed by the feel of the strap itself and the sturdy stitching.

The only concern I had before my S2 Delta arrived was that the clips where you can change out weapon connectors were plastic.

However, when I tried out these clips, I quickly realized there was nothing to worry about.

They are made of extremely hardy plastic like the kind you trust on your kid’s car seat that you know won’t let you down when push comes to shove.

Up by your shoulder, the strap is a nice two inches thick that helps distribute the weight of your AR over a larger area and makes it less painful to carry for a long time.

Then, once you get closer to where your weapon interfaces with the sling, the strap narrows to one inch making it so that you aren’t fumbling with a bunch of extra material in the way of your weapon connection.

As soon as I strapped this sling onto my AR, I knew the light weight of the sling did nothing to minimize its durability.


On top of its sturdy construction, the S2 Delta sling has some amazing features that make it convenient and easy to use.

My favorite feature is the quick-adjust strap on the lower section of the sling that makes it super easy to pull your weapon into place with only your forward hand.

Sometimes these quick pull adjustment straps are tough to manipulate, but not the S2 Delta.

It made transitions between carrying on my back to my side virtually flawless.

This strap also made it so that when I drew up my AR to fire, I could tighten the quick adjust to stabilize my shots and ultimately improved my accuracy.

Even when wearing body armor, this sling will adjust to fit anybody and has an incredible range of 41 to 60 inches of adjustability.

The other feature I love about this sling is that it’s got modular attachment options.

You can choose between the standard pigtail attachment or upgrade to a push-button quick detach, locking stud swivel, or even a C.L.A.S.H. hook attachment that fits an HK.

Basically, you can make this sling fit any type of mounting hardware.

Another thing I like about this sling is that it’s made with a D-ring to allow the transition from a two-point to a one-point carry.

Is the S2 Delta Sling Worth It?

If you need a comfortable and reliable sling for your AR that gives you all the features you need to improve your shooting, then the S2 Delta should be your first choice.

S2Delta - USA Made Sling Connector End Accessory, C.L.A.S.H. Hook, M.A.S.H. Hook, Push Button Swivel, or Pigtail,
  • Connectors for attaching S2Delta rifle sling with weapon.
  • Designed and assembled in USA with entirely USA made components. S2Delta’s slings are made with the highest quality components available.
  • Avialable in several connector options to meet your need

Here’s why. It’s:

  • Well-made
  • Adjustable
  • Modular
  • Lightweight

I’ve used a lot of high end AR slings over the years, but from now on, I plan on using the S2 Delta.

2. Tactical Hero Rifle Sling: Best Tactical Sling

The Tactical Hero 2-Point Rifle Sling is the best tactical sling you’ll find on the market today.

When you’re hiding in the brush stalking your target, or when you’re using your favorite turkey call to lure in some birds, you need to have your rifle ready to go at a moment’s notice.

This rifle sling gives you the perfect way to do so.

It’s made of sturdy materials, features a 26” adjustment range, and comes with Tactical Hero’s satisfaction guarantee.

It’s also very inexpensive, which leads us to this question:

How well can this bargain sling hold up?

Let’s find out!


The Tactical Hero 2-point BDS sling is made with high-quality nylon.

It’s 1.2” wide to provide a proper fit on all sling swivels, and can also connect to sling loops.

It fits every kind of attachment hardware, and includes two HK-style clips with elastic covers.

The clips, straps, and stitching on this sling are all very high-quality, and the elastic covers add a nice finishing touch.

The sling also features an adjustable shoulder pad with a velcro loop to keep it in place.

There isn’t really any cushion-y padding on it, but the sling webbing is wide enough that it’s not uncomfortable.


This sling features a quick-adjust system that lets you shorten or lengthen the sling from 30”-56”. All you have to do is pull the adjuster buckle to set it at the perfect position.

The adjustment system works pretty well, although the buckle can be a bit stiff at first.

It does loosen up over time and with continued use, but you might need to use two hands to adjust it at first.

On the bright side, this stiffness means it won’t slip at all while you’re using it!

The 26” adjustment range makes it one of the most adjustable slings available, and it fits people of all ages and sizes well.


The BDS sling is available for just around $24 online.

For a sling on par with those two or three times more expensive, and one that comes with the Tactical Hero guarantee, this is a very good price.

Plus, should you ever have any issues with your sling, Tactical Hero is a great company that provides excellent customer service.

3. STI 2 Point Rifle Sling: Best Two-Point Sling

The STI 2-Point Rifle Sling is the best two-point sling available.

It’s very strong and robust, incredibly versatile, and comes at an unbeatable price!

What makes this sling so durable and reliable?

Let’s find out!


The STI 2-Point Sling is made with a two-layer nylon “tube woven” webbing.

This flat, tubular webbing looks and feels like one layer, but provides the increased strength of a two-layer design.

The strong Box X stitching and durable, high-impact polymer composite sling buckle provide military-grade reliability while still keeping the sling soft and flexible.

It’s strong, tangle and chafe resistant, and very comfortable to wear.

The webbing is 400 lb tested and weatherproof, meaning it will not be weakened by inclement weather conditions like rain, snow, or freezing temperatures!

The high-quality construction of this sling gives me confidence that it’ll last for many years to come.


The simple, versatile design of the STI 2-Point Sling allows for easy attachment to almost any rifle or shotgun.

It doesn’t come with any extra hardware, but it is compatible with all 1.25” attachment hardware, including:

  • ITW Mash Hooks
  • HK Hooks
  • Paraclips
  • OEM Rifle Sling Swivels
  • QD Swivels

It’s pretty easy to attach to a range of firearms, but if you have any trouble threading the webbing, there are a ton of videos on YouTube that show you how to attach it properly with any hardware.


The fast adjustment system allows you to quickly lengthen or shorten the sling without having to disconnect it, minimizing the risk of tangling or fumbling.

It’s adjustable down to 30” and up to 55”, which makes the sling perfect for shooters of all sizes and ages.

This sling features a simple thumb loop adjustment system.

The loop is large enough to make fast, easy adjustments without fumbling, even while you’re wearing gloves!

The two-strap adjustment system allows for nearly endless adjustments, letting you fit the sling perfectly to your body, your rifle’s stock, and your preferred shooting position.

If you need a 2-point sling that can adapt to any shooter and firearm, you can’t go wrong with the STI.


The highly-adjustable nature of the STI 2-Point Sling greatly improves your target acquisition and shooting times.

Once you adjust it to your specific fit, it allows you to snap-to a firing position very quickly, no matter what kind of firearm you’re using!

There are no clips or shoulder pads included, keeping the sling’s weight down to make carrying comfortable.

Even though it doesn’t include any extra padding, it’s still very comfortable to wear, even for extended periods.

It’s easy to attach and can be used with a wide variety of firearms.

If you need just one sling that can adapt to every rifle or shotgun you own, this is the one to go with.


The STI 2-Point Rifle Sling costs just around $25.

Some shooters don’t have hundreds of dollars to drop on things like premium slings or hunting boots, but still need quality gear.

The STI sling is perfect for people who need something sturdy on a budget.

It’s very affordable, offers premium quality, and even comes with a 100% customer satisfaction guarantee!

If you have any problems or questions about your sling, STI offers excellent and responsive customer service.
