The 5 Best 5.56 Suppressors for Your Rifle

We may earn a commission when you purchase through the links on our site. Find out more here.

Do you want to go partially deaf in an old age, or do you want to buy a new toy for your rifle? Maybe that is a bit dramatic, but a suppressor will help reduce the loud bangs. They’ll also help control the muzzle rise and recoil. Letting you place follow on shots nice and central. And of course, they also reduce the muzzle flash.

Contrary to what most people see in movies, suppressors only reduce the sound of the gun — it doesn’t totally make the gun silent. So remember to use hearing protection when you can.

Here’s a summary table of the best 5.56 suppressors that you can buy today.

Silencer vs. Suppressor: What’s the Difference?

Image source: On Target Magazine

Suppressors are usually constructed of metals like stainless steel or titanium. They feature a cylindrical shape equipped with sound barriers and a hollow bore where the projectile can exit.

Some folks believe suppressors have something to do with the muzzle flash. Meanwhile, some say silencers can substantially reduce the sound of your gun.

Some also say that silencers can make the guns quieter than a suppressor.

But whatever you call them — suppressor, silencer, or sound moderator — all are interchangeable and refer to the exact same thing.

There is no difference between a suppressor and a silencer. Both terms refer to a device that helps reduce the sound of a firearm shot.

How Does a Suppressor Work?

Let’s first talk about what happens in a typical gunshot.

When you shoot a gun you create a mini-explosion releasing a lot of high-pressure gases. These propel the cartridge forward but also create the big bang we hear.  

Suppressors work by lowering the pressure and velocity of the gases by slowing them down as they exit the barrel. They basically lead the gas through a long and convoluted path before it can exit the barrel while allowing the bullet to go straight through. This reduces the energy in the gas and we get a much lower thud instead of a big bang.

Here’s a video showing how suppressors work:

Why Get a Suppressor for My AR-15? Pros and Cons

  • Reduced noise: A suppressor substantially reduces noise which is ideal for indoor shooting and home defense.
  • Versatile: Some multi-caliber suppressors enable you to swap between calibers.
  • Reduced recoil: By trapping the explosive gases that leave the barrel after a gunshot, a suppressor helps reduce felt recoil.
  • Reduced muzzle rise: Trapped gases in the suppressor lead to less muzzle rise and a more comfortable shooting experience.
  • Increased accuracy: Less recoil and less muzzle rise result in easy handling and tighter target groups.
  • Still loud: You might still need to use subsonic ammo to make it even quieter if you are James Bond on a mission.

Below is also a video about the basics of getting a suppressor for your AR rifle:

How to Install a Suppressor on Your AR-15

Before we talk about how to mount a suppressor on your AR-15 rifle, we need to discuss the two types of suppressors out there. They are direct thread and quick-attach.

Direct Thread Suppressors

The simplest and common form of a suppressor. It’s so simple to install that you only need to screw it directly on the AR-15’s threaded barrel. Quick and easy.

Here’s a video below showing how to attach a direct thread barrel suppressor:

Quick-Attach Suppressors

Quick-attach suppressors are also called Quick Detach or QD Suppressors. They’re the ones you can install using another muzzle device, such as a muzzle brake or a flash hider.

To install QD suppressors, first, you need to thread the muzzle device on the barrel of the gun. Then, you can mount the suppressor on that device — and you’re ready for some action — a quieter one, that is.

Direct Thread Vs. Quick Attach: Pros and Cons

Direct Thread

  • Lightweight and shorter
  • No need for a muzzle device for attachment
  • Consistent return to zero
  • Straightforward to install and use
  • Easy to maintain
  • More affordable
  • Can come off unscrewed on their own if you are lucky enough to have a lot of ammo for a long session.
  • You can only install a specific suppressor in the same specific thread pitch

Quick Attach

  • Getting a flash hider or muzzle brake on your rifle
  • Does not need to reattach the added muzzle device when not in use
  • Less likely to back off from the barrel
  • As in the name, it is quick to attach and remove
  • Offers a way to attach suppressors to unthreaded barrels
  • Usually costs more
  • Heavier

Suppressor Types

Here’s a thorough video by Shoot Wise about the suppressor types.

Suppressors are legal to buy and use in almost all states. California, Delaware, the District of Columbia, Hawaii, Illinois, Massachusetts, New York, New Jersey, and Rhode Island are the eight states that don’t allow private ownership of silencers. You can take a look at the American Suppressor Association’s map to see the rules for your state.

The YHM Turbo 5.56 silencer is one of the most cost-effective suppressors on the market without compromising on quality. I love the durable stainless steel of this one. It has a lightweight feature and an easy ratcheting QD mechanism. Even though it’s tubeless, this silencer is durable due to its solid construction.

In addition to its tubeless design, this suppressor improves the firearm’s internal volume.

The YHM Turbo also sports a strengthened baffle made of Inconel. It’s a machined hard nickel alloy commonly used in suppressor construction.

I can say that the YHM Turbo is a highly effective and flexible suppressor. This suppressor sports efficient concussive force and gun noise reduction. It also has excellent features like its 1/2-28 threaded 3-port muzzle brake and simple installation. With this gun attachment, you can quickly and easily switch between mounting types.

The new SOCOM556-RC2’s enhanced internal venting is an excellent addition for a lower cycle rate and less gas blowback. The revised model features a blast shield integrated into the back panel. Therefore, improving this suppressor’s durability.

Aside from these features, it has a full-auto rating, superior sound suppression and accuracy, and excellent repeatability. It is safe to say that the OSS HX QD-556 Ti enhances the performance of your firearm.

The Beast Dominus efficiently minimizes the blowback without sacrificing noise reduction. Its SR brakes also work with all SR suppressors.

  • Excellent repeatability
