Best AR-15 Muzzle Brakes (2021 Review)

A muzzle brake is an easy, convenient way to reduce recoil and muzzle climb, making your shooting more accurate. For that reason, they’re an incredibly popular upgrade for modular rifles like the AR-15.

But how exactly do muzzle brakes work? And how do you know what muzzle brake is right for you? 

We’ll answer those questions and more in this handy guide. First, we’ll talk about what, exactly, a muzzle brake is, how muzzle brakes work, and how they’re different from (and similar to) other muzzle devices. 

Next, we’ll discuss how to choose the best one for your particular purposes. Finally, we’ll then give you our top 5 recommendations for AR-15 muzzle brakes to help you get started on your search. 

Now let’s dive right in.

What Are AR-15 Muzzle Brakes?

As we’ve already stated, a muzzle brake reduces felt recoil and muzzle jump. That means that the rifle moves less after each shot, which allows for faster and more accurate follow up shots.

A muzzle brake is not the same as other muzzle devices like compensators and flash hiders. A compensator is quite similar but has holes in the top to vent gases to prevent muzzle flip while doing little to nothing about recoil. Now technically a muzzle brake doesn’t actually do much about muzzle flip and primarily fights recoil.

However, many muzzle devices are actually hybrids of the different types of muzzle devices, and muzzle brake and compensator hybrids are particularly common. That’s why muzzle brakes are generally thought to mitigate both flip and recoil. In fact, it’s not uncommon to hear “compensator” and “muzzle brake” used more or less interchangeably these days. 

A flash hider, or flash suppressor, is a muzzle device that handles the other side of the muzzle blast: muzzle flash. They have no effect on recoil or muzzle movement on their own, but they do reduce muzzle flash and noise. Muzzle brakes with flash hiding capabilities are less common, but still relatively easy to find. 

Because they’re a barrel attachment, muzzle brakes need to be the right caliber. For an AR-15 rifle, that’s generally .223 Remington/5.56 NATO ammo. However, just like there are AR-15s in different calibers, there are also muzzle brakes for different calibers, such as .300 Blackout. 

AR-15 muzzle devices typically use standard 1/2-28 threads, but that varies based on caliber. Still, regardless of caliber, a barrel or muzzle device that doesn’t use that standard configuration is quite unusual, so you shouldn’t have to worry about this too much. 

How Do AR-15 Muzzle Brakes Work?

Okay, so you know what a muzzle brake is supposed to do, but how does it do it?

Well, when a gun is fired, gases and particles are released. These gases force the bullet out of the barrel, but they also jar the weapon up and back as they exit the muzzle. 

A muzzle brake contains expansion chambers and baffles, which provide room for the gases to, well, expand, and reroute them through holes in the side of the muzzle brake. That sends the gases out to the side, rather than forward. 

Holes may be drilled at a backward angle, rather than perpendicular to the barrel, to direct the gases backward as well, further combating recoil. 

The placement of the holes affects the direction of muzzle movement by controlling the direction of gas flow and therefore the direction of energy relative to the firearm’s center axis (long ways). Muzzle brake/compensator hybrids will typically have holes along the top of the device, as well as the sides, to redirect gas upwards, combating muzzle rise. 

Even something as small as the direction of the barrel’s rifling affects muzzle jump, so hole placement needs to take that into consideration.

That means that you need to be sure that your muzzle device lines up properly once on your AR-15 barrel. If your barrel’s rifling has a right-hand twist, as most do these days, you’ll need to line up the top gas ports a little to the right of the center. You may need to go through some trial and error before you figure out exactly how your muzzle brake needs to be positioned.

What Do You Look For In The Best AR-15 Muzzle Brakes?

When choosing a high-quality muzzle brake, there are a few things to consider:


We’ve already covered that most muzzle brakes on the market now are actually muzzle brake/compensator combos. We’ve already discussed the benefits of those, so let’s go ahead and talk about muzzle brake/flash suppressor combos.

Flash suppressors minimize muzzle flash and noise, which protects your hearing, protects night vision devices in low light, and avoids the telltale flash giving away your position in a self-defense or home defense situation. All of those advantages carry over to a muzzle brake/flash suppressor hybrid as well.

And flash suppressor hybrids are often actually hybrids of all three of the muzzle devices we’ve talked about here with the advantages of each.

However, just like with anything else, the more features you add, the higher you can expect the price to be — or the worse you can expect the device to be at each of its functions. So be sure to consider your budget and how you prioritize those different features to get the best muzzle device for you and your budget.

Minimal Side Blast

Side blast refers to the shockwave that comes out of the side of a muzzle brake as a result of its redirection of the gases. It’s not especially important, except that people shooting next to you will find it annoying. Depending on where and how you’re shooting, it may also kick up dust, but mostly wanting minimal side blast is just a polite thing. Still, manners matter. 

Easy Installation

Overall, muzzle brakes are very easy to install. However, there is typically some hardware involved, such as crusher washers or shims, and that hardware may or may not come with the muzzle brake. 

Make sure you know what hardware is necessary and whether or not you need to purchase it separately from the muzzle brake.

Of course, you also need to make sure it has the proper threading to fit your barrel. For AR-15s, the standard barrel threading is 1/2″ x 28.

Final Thoughts On AR-15 Muzzle Brakes

There are a ton of great muzzle brakes on the market, but unfortunately, we’re limited to just five picks, so I want to give shout outs to a few other awesome options before we part.

Each of the brands above makes multiple excellent muzzle devices in addition to the ones we’ve listed here. The Precision Armament EFAB and Precision Armament Hypertap, for example, are a couple of our other top muzzle brake picks, though we left them off this list in order to highlight some other great brands.

And speaking of other great brands, we didn’t have room to include muzzle brakes from Surefire, Dead Air, Odin Works, or Smith Enterprise, but they’re other great brands worth checking out if none of our top five are exactly what you want.
