The overall best AR 556 accessory is up first. The remaining AR 556 accessories will be presented in order of importance.

The accessories that I recommend you pick up first are up first.

The accessories that you can add to your AR-556 at your convenience are near the end.

One last note: there are plenty of different AR-556 models. I’m assuming that you have a base model, here. If your AR-556 already has something I mention, I apologize. You can skip that one.

1. Blue Force Gear Vickers 2-to-1 Unpadded Sling - Overall Best AR-556 Accessory

Blue Force Gear slings are my go-to slings for just about everything. The Blue Force Gear Vickers 2-to-1 Unpadded Sling is one of their most versatile slings. I’ve found that I can just slap this sling on my rifle. And it gets the job done, regardless of what I’m doing.

The main benefit of this sling is that it can be used in a 1-point or a 2-point configuration. There are times when a 1-point sling is an ideal option. And there are contexts where you definitely want a 2-point sling.

This sling can do both. And the 1-to-2 point system is super simple. It’s just a simple sling swivel attachment that’s easy to use with one hand because it sits flat against the sling webbing. So when you push the QD sling swivel with your thumb, it simply pops into place.

Additionally, the sling adjustment system is also super easy to use. There’s a thick fabric tab that you pull to tighten or loosen the sling.

Admittedly, it’s easier to loosen the sling than it is to tighten the sling. But I think the adjustment tab system is the best compromise between functionality and snag-free simplicity.

The last thing I’ll say is that the Blue Force Slings are super durable. The webbing is thick. And all the hardware is either metal or high-density polymer.

I’ve got a few of them in my inventory. And I’ve never had anything break. So you can count on this sling when you need it.


  • Can be configured as either a 1-point or 2-point sling.
  • Transitioning from 1-point to 2-point, or vise versa, is quick and easy.
  • Simple and efficient adjustment system.
  • Thick webbing and tough hardware.


  • Tightening the sling takes a bit more effort than loosening it.

A light is one of the most valuable accessories for any gun. You can’t shoot at what you can’t see. And, with a rifle, a weapon-mounted light is pretty much mandatory, unless you’re going to one-hand your rifle like Arnold Schwarzenegger.

So the Streamlight ProTac Rail Mount 2 Fixed-Mount Long Gun Light is one of the most valuable accessories you can get for your AR-556. It enables you to use your rifle in almost any context.

But the main thing about this light is that it’s more affordable than many other weapon-mounted lights. And it’s actually a good piece of equipment. It won’t stop working after you’ve owned it for 37 seconds, like many of the cheap lights on the market.

Additionally, this light comes with everything you need, including a remote switch and picatinny rail mounts for the remote switch. So you don’t have to use zip ties for anything but cable management.

It mounts to a picatinny rail. So you may need to purchase a rail section, if your handguard only has M-LOK or KeyMod mounts. But, other than that, you can mount this light up and go, right out of the box.

The only downside is that this light only puts out 625 lumens. Don’t get me wrong. The light output is more than enough for target identification in almost any context. However, you can get lights that put out 1000 or more. They’re just more expensive.

But, overall, there’s a lot to like about this Streamlight light. It’s affordable. And it meets the demands of most civilian shooting and even the needs of tactical professionals.


  • One of the most affordable lights on the market that doesn’t suck.
  • Includes everything you need, including a remote switch and remote switch mounts.
  • Super simple thumb-screw picatinny rail mount.
  • 625 lumens is bright enough for just about any type of shooting, defensive or otherwise.


  • You CAN get brighter lights, they’re just more expensive.
  • Only mounts to a picatinny rail.

I had debated whether this was more important than the light. But I decided that being able to use your rifle was more important than having a dedicated place to store it.

But, being able to securely store your rifle is important. That’s why the Plano Molding All Weather Tactical Rifle Cases is on the list before anything that might be considered an upgrade.

There are two reasons why this is an important accessory to have:

  1. It protects your rifle from things like water, which will cause it to fail.
  2. This case can be locked to help keep children, burglars, and anyone else from accessing your rifle when you’re not around.

So this case keeps your rifle in working condition. And it gives you a way to secure your gun without getting a gun safe. However, a gun safe is inarguably more secure. And there are better ways to stage your rifle, if you want to keep it ready for home defense.

But this Plano Molding case is weather proof, which is nice if you shoot outside. And the outer shell is fitted with a relief valve that keeps your case from exploding when the pressure changes from temperature or altitude.

It’s also got a perforated foam insert which you can easily cut to fit your firearm. That way your AR-556 doesn’t bounce around in transit.

Overall, it’s just a really solid gun case. And a gun case is useful for just about everything you do with your rifle, from storage to heading out to shoot.


  • Weather proof to keep your rifle dry and operational no matter what.
  • Lockable to help keep your AR-556 secure.
  • Relief valve to resist pressure changes from altitude or temperature.
  • Perforated foam insert that can be customized to the shape of your gun.
  • Rugged construction with spring-assisted latches.


  • Not as secure as a gun safe, if you use this case for secure storage.

As far as I know the AR-556 comes with a standard mil-spec charging handle. Mil-spec charging handles suck, even for right-handed people. If you’re left-handed, it’s even worse.

The Radian Weapons Raptor Ambidextrous Charging Handle is good for everyone. It’s one of the best charging handles you can get, end of story.


Mainly because the latch design is the easiest to use, regardless of whether you’re left-handed or right-handed. The latches enable you to pull the charging handle straight to the rear, without any of the binding that you often get with mil-spec charging handles.

Also, the latches are skeletonized. So this charging handle doesn’t even weigh that much more than a mil-spec charging handle.

And everything is pinned. No screws. This charging handle is super durable.

Last thing, then I’ll stop ranting about how rad this charging handle is: even though the latches are enlarged, they don’t present any real snagging issues. Even with the largest Raptor charging handles—which have offensively large tabs—there’s no snagging issues.

This Radian Weapons charging handle is a simple, straight over upgrade for your AR-556. You don’t have to give anything up to get much easier and faster operation.

Well, except money. This charging handle is significantly more expensive than a mil-spec charging handle. But it’s worth it.


  • Makes it super easy to pull your bolt to the rear without the binding you sometimes get with a mil-spec charging handle.
  • Ambidextrous. And it’s just as easy to use if you’re left-handed.
  • No screws. Exceptionally durable construction.
  • Skeletonized latches keep the weight to a minimum.
  • Extended tabs aren’t a snagging issue.


  • Expensive.

Many of the AR-556 models come with a fixed front sight post or a polymer rear sight. In either case, a solid rear sight can’t hurt.

The A.R.M.S., Inc. Low Profile Flip Up Rear Sight is pretty much the only flip-up rear sight that I use anymore. There simply aren’t any others that are as durable or as capable.

There are two main reasons for this:

This sight is almost entirely metal. The only thing that’s polymer is the small rear aperture. Also, the locking system is a metal bar that captures a notch on the top of the sight.

So this rear sight is bomb proof.

The other reason I almost exclusively use this sight are the apertures. Both the large and small apertures have an overhold notch for making longer shots. Even though this is technically a battle sight, you can still use it to get hits at longer ranges, where you’d need an overhold.

Other than that, everything is pretty standard. It lays down flat enough to be out of the way of just about any optic.

And it attaches to a picatinny rail with a single screw.

The biggest downside to this ARMS Inc rear sight is that it’s also pretty expensive. It’s awesome. But I can’t deny that there are far more affordable rear sights out there. But they’re not quite as capable. If you want functionality, this rear sight is the way to go.


  • Almost entirely metal.
  • Locks down super securely. Will not pop up if you don’t want it to.
  • Overhold notch for shooting at longer distances than your rifle is zeroed for.
  • Lays down flat enough to stay out of the way of any optic.


  • Expensive.

Want to put the best foregrip ever on your rifle? Get the Bravo Company MFG BCMGUNFIGHTER Vertical Grip-Mod 3. Thanks for coming to my TED talk.

Just kidding.

But seriously, this is probably the best all-purpose foregrip you can get.

The main reason is that you can use it for almost any grip technique. It’s long enough that you could use it with a vertical four-finger grip, if you want.

However, it’s got a good shape and a very slight angle that makes it ideal if you use a more modern thumb-forward or thumb-over grip. It provides a really good leverage point to pull your rifle into your body for more stability and better recoil management.

And, even though it’s a good grip point, it’s also compact enough that it presents very little risk of snagging.

This Bravo Company grip also has a really nice grip texture that’s not too abrasive. But it’s good enough that you won’t have any issue with slipping, even when your hands are sweaty or oily or whatever.

Lastly, this grip attaches to an M-LOK rail. So it’s compatible with the free float rail that comes with the AR-556.

However you’ll either need to upgrade your rail or get an adapter if you have an AR-556 with the classic A2 handguards.

But, no matter how you need to attach it, this is easily one of the best foregrips you can get for any rifle.


  • Excellent ergonomic design works well for any forward grip technique.
  • Slight angle is excellent for pulling the rifle into your body with a thumb-forward or thumb-over grip.
  • Compact enough to minimize snagging issues.
  • Grip texture is grippy, but not too abrasive.
  • Attaches to an M-LOK rail.


  • Requires a handguard upgrade or an adapter if you want to mount this grip to an AR-556 with a classic A2 handguard.
