If you’re looking for a quick and easy way to customize the look and performance of your AR-15, start by upgrading the muzzle device.
A muzzle device is exactly what it says; a device that attaches to the muzzle of your rifle barrel. Almost all AR-15 rifles have a threaded barrel, so this is something anybody can do without having to pay a gunsmith or your local gun shop to install.
Flash Hider vs Muzzle Brake
Muzzle brakes are made with the purpose of reducing felt recoil, resulting in improved accuracy and the ability to swiftly fire follow-up shots. On the other hand, flash hiders are designed to minimize the visible muzzle flash and protect the shooter’s vision during low-light or nighttime conditions. When it comes to choosing the right muzzle device for your firearm, it ultimately depends on your shooting style and personal preferences.
Most of the gasses are burned up in the process depending on the length of the barrel, but there are some that escape the muzzle as the bullet leaves the barrel. The ‘un-burnt’ gasses that leave the barrel have a tendency to combust when it comes into contact with the oxygen-rich air outside of the gun. This chemical reaction causes a brief but bright fireball known as muzzle flash. Flash hiders are designed to disrupt that reaction to the oxygen-rich air, thus reducing or eliminating the muzzle flash.
Muzzle brakes reduce the amount of felt recoil. The flat, wall-like surfaces of the muzzle brake’s chambers redirect the escaping gasses to the sides of the shooter instead of downrange. This redirection of the escaping gasses counters a portion of the rearward movement that produces felt recoil in the hands and shoulder.
What are the Different Type of Muzzle Devices?
Each of the different muzzle devices serves a specific purpose. Depending on what your needs are, the right muzzle device will enhance the performance of any AR-15.
The flash hider is designed to disrupt the escaping gasses with the goal of greatly reducing or eliminating the muzzle flash. Generally the shorter the barrel, the brighter and more violent of a flash you’ll experience.
Hiding or eliminating the muzzle flash is extremely important when shooting at night or during low light conditions. Consequently, the visual signature of your position will be much harder for others to see and identify.
The muzzle brake redirects the escaping gasses to the sides (180 degrees from the shooter) reducing the rearward recoil of larger caliber rifles. The reduction in recoil allows the shooter to retain better control of the weapon for follow-up shots.

Does a Muzzle Brake Hide Flash?
While a flash hider is intended to reduce visible flash, a muzzle brake is designed to reduce recoil inherent to larger cartridges such as the 7.62 and typically does not reduce visible flash.
Do Muzzle Brakes Make Guns Louder?
Muzzle brakes are not for everyone. In all fairness, muzzle brakes do have a couple of disadvantages. They add up to 3 inches of length of the barrel, will slightly reduce the velocity of the round, and they are LOUD.
They don’t necessarily make the shot louder, although it sounds that way. The reason why they sound so loud to shooters on the range is that a muzzle brake is designed to vent the gasses to the sides of the muzzle instead of just letting the gasses flow straight out of the muzzle.
Other shooters in close proximity will often find the sound to be louder than normal. This is typically a result of the shockwave being redirected to the sides as opposed to the sound itself.
Do Muzzle Brakes Improve Accuracy?
Muzzle brakes can make rifles more accurate due to the reduction in recoil. Muzzle brakes allow the shooter to better track the flight time of the bullet and bullet impacts. Many Prairie dog hunters will use muzzle brakes on their 22 centerfire rifles in order to maintain their site picture after taking the shot.
Muzzle brakes are indispensable for military and law enforcement snipers as well as long-distance competition shooters who must keep their sight picture during recoil to observe the bullet strike. Just about all sniper rifles, even the heavier .308s that have reduced felt recoil, now come with muzzle brakes as part of the build.
Does The Military use Muzzle Brakes?
The Army is testing a muzzle device called the Smuzzle. It’s a hybrid design that reduces sound, brakes recoil, and suppresses the flash. Three Army researchers developed the Smuzzle while working on the U.S. Army’s Next-Generation Squad Weapon (NGSW) program.
It’s a hybrid device that cuts half the volume at the shooter’s ear, reduces recoil by a third, and drops volume down range by one quarter, said Gregory Oberlin, a small arms engineer at the Army’s Combat Capabilities Development Center Army Research Lab.
The prototypes only add 3 inches to the overall length of the NGSW platform. The weight of the Smuzzle muzzle device is a half-pound for the NGSW, somewhat heavier for other weapons systems. The heavier weight is expected in order to sustain a 600 rounds per minute rating.
While the Smuzzle was purpose-built for machine guns, changing the dimensions and specifications is only a matter of scaling, Oberlin said.
What Flash Hider Does The Military Use?
The Vortex Flash Hider is used by the US Military on M4 carbines with the NATO Stock Number of NSN 1005-01-591-5825, PN 1001V.
The Vortex Flash Hider made for AR15 rifles weighs 3 ounces, is 2.25 inches in length, and does not require a crush washer for installation. The use of a crush washer was rejected as its use can increase visible flash from the shooter’s perspective. By design, The Vortex Flash Hider self-tightens to the barrel during sustained firing.
The Vortex Flash Hider has been called the “most effective flash hider available short of a (sound) suppressor" because it reduced the flash by 99% during testing. Although the Vortex flash hider seems to be the superior option, many issued M4 and M16 variant rifles come with the A2 flash hider.
Is the A2 Flash Hider Any Good?
The A2 flash hider is a really good flash hider for several reasons. Yes, there are other flash hiders on the market that hide the flash a little bit better, but for the price of an A2 flash hider, you really can’t go wrong. It’s been a proven design for many many years before the market was flooded with many new designs. Some will say that the A2 flash hider sucks, but we disagree. Here’s why.
- The A2 birdcage flash hider is a really good flash hider. Maybe not as good as some of the newer designs such as the Vortex Helix or Manticore, but it definitely holds its own in a flooded market. Considering that a bare muzzle averages 10,700 LUX when fired without a muzzle device, the A2 flash hider reduces that flash to 0.48 LUX! Considering that the Manticore Arms Eclipse claims to eliminate muzzle flash, it comes in at 0.43 LUX. The A2 really does hold its own.
- It’s compact size. Most muzzle devices are between 2 and 3 inches in length whereas the A2 comes in at 1.75 inches. At this compact size, the A2 flash hider is still very effective.
- Compared to other muzzles devices on the market, the A2 flash hider is damn near free in terms of price. The majority of muzzle devices will be north of $50, but the A2 comes in at a very affordable price point; somewhere between $6 and $10 depending on where you shop.
