A muzzle brake not only has functional advantages, but it also gives your weapon a mean, tactical appearance. The 300 AAC Blackout round was developed for use by special forces in a variety of operational situations.

The right muzzle brake for the 300 AAC caliber can be found by following our guide below.

What is a Muzzle Brake and How Does It Work?

Muzzle brakes are threaded objects that attach to the end of the barrel and redirect the propellant gases generated by round each fired. This accomplishes two goals. For starters, it lessens the sensation of recoil. Second, they can be made to lessen the muzzle rise.

All of these features improve the shooter’s comfort, power, and precision by making it simpler to make follow-up shots. Recoil may be reduced by ten to fifty percent using muzzle braking.

Their efficacy is determined by a variety of variables, including caliber, design, and the height of the barrel profile above the stock.

Design of a Muzzle brake 101

Muzzle brakes were first used on artillery pieces like anti-tank cannons, where recoil would cause significant logistical issues. They come with a variety of variations when mounted on rifles or carbines.

Scoop 

The basic scoop seen on the end of an AKM rifle is a classic style. This tends to reduce the AK’s annoying and constant muzzle rise.

Venting

Integrated venting or porting, which consists of a series of upward-facing drill holes that allow gas to escape and force the muzzle down, is often very popular.

Attaching it on the firearm itself

The majority of muzzle brakes are threaded into the barrel’s top. Others are bent, clamped, or pinned in place.

Reduction in Recoil

The anti-recoil effects are given by a special configuration of slots or vents, regardless of how it connects to the barrel.

Compensators are devices that are only intended to suppress muzzle raise but not recoil.

How to select the Best Muzzle Brake for Your 300 Blackout

The below are the most important characteristics to search for in a modern muzzle brake:

Attachment Technique

The form of connection is the most important consideration when selecting a muzzle brake. Only a gunsmith may add some muzzle brakes.  Many (like the ones in our ranking) twist or thread on.

The kind that is pinned to your barrel, on the other hand, is the better choice (like the ones in our ranking). This provides the safest connection to your barrel. Muzzle brakes that clamp on are another good choice.

Dimensions and Weight

Aside from the method of attachment, it’s critical to get one that’s the right size and weight for your caliber and rifle. The added weight at the end of the barrel can alter the rifle’s handling and balancing. Also a slight shift of equilibrium may have an effect on precision.

Venting and Flash Suppression

Flash suppression is available on some muzzle brakes. The baffles and vents may be adjusted to minimize muzzle blast and keep your location hidden. There are no vents on the bottom of several of them. This keeps them from swirling dust around and obscuring your view.

2nd Best 300 Blackout Muzzle Brake: GENTRY CUSTOM LLC – QUIET MUZZLE BRAKE 30 CALIBER

2nd Best 300 Blackout Muzzle Brake: GENTRY CUSTOM LLC - QUIET MUZZLE BRAKE 30 CALIBER

Pros

  • Easy to atttach
  • The Intricate Network of Internal Chambers Disperses Gases & Blast Noise to Eliminate the Recoil felt
  • Awesome grey finish

Cons

  • Blast Noise is Still Very Loud

GENTRY CUSTOM LLC is a tiny Texas-based manufacturer of muzzle brakes. They’re thin, but they’re not flimsy; these are high-quality, handcrafted products.

The architecture of this .300 caliber model is deceptively basic. Three roles are provided by a dense, symmetrical matrix of round vents. For starters, it reduces muzzle blast. Second, the muzzle increase is reduced. The network of venturi expansion chambers concealed inside the muzzle brake significantly improves the third feature, recoil power. For the greatest recoil protection and blast reduction, these venturi chambers diffuse and redirect gases.

There are openings that are both longitudinal and perpendicular to the bore in this surprisingly complicated arrangement. These holes aid in evenly dispersing gases and noise around both directions.

This piece is offered in two finishes: black steel and matte 416 stainless steel. This have a traditional design that hides a shocking amount of complexity. The thread-on architecture is quite reliable and it’s simple to set up.

Verdict

This is a deceptively complex muzzle brake manufactured in the United States by a local Texan corporation.

The effectiveness of its venturi chambers and the finish options are two of its best qualities. This is a fantastic choice.

Everything to know about muzzle brakes

Most hunters know muzzle brakes and flash suppressors mainly from military small arms or from guns. Artillerymen and members of the armored forces understand muzzle brakes as huge, somewhat bulky terminations of the gun barrel. As a rule, little is known about their effect. They are said to slow down the recoil, which leads to a higher possible firing frequency.

The principle is simple. When an inflated rubber balloon is released, it fizzles out in the opposite direction, ejecting the air. The sound it makes is due to the air vortices it emits. The principle of reaction and counter-reaction has been known for a very long time and is commonplace.

Examples are hairdryers, firework rockets and jet engines, but also the released garden hose. Airline passengers are familiar with the incredibly strong braking effect that can be felt after thrust reversal after landing. The first thing that comes out of a gun barrel is a bullet, closely followed by a gush of hot gases.

All classic firearms work on the principle of igniting powder, which is capable of building up high pressures in the barrel in a flash. When the bullet is about to leave the Best 300 Blackout Muzzle Brake, pressures of 400 to about 700 bar are still present in the barrel.

This varies with the barrel length, the type of powder and the caliber. These are very high pressures. They leave the barrel at several times the speed of sound with corresponding noise development (shot bang).

Design of muzzle brakes

With powerful cartridges, such as 300 Win. Mag. or 8x68S, good manufacturers offer barrels with muzzle brakes. Several holes are drilled radially into the barrel in the area of the Best 300 Blackout Muzzle Brakes. This must be done before the barrel is rifled, as drilled holes leave a tiny burr where they enter the barrel bore, which is difficult to remove. An expensive machining alternative is “drilling” using spark erosion technology.

This allows holes and even slots to be added to a barrel after the fact. The most elegant way to attach a muzzle brake is to thread the end of the barrel. The simplest option is a slotted piece of tubing that fits straight over the barrel and is fastened with clamping screws.

Best 300 Blackout Muzzle Brakes

Direction of holes is critical The direction of the holes ultimately determines the direction of the braking effect. Bores at the top cause a reduction in the upstroke of the rifle barrel due to the recoil effect of the powder gases escaping upwards. Lateral bores – if symmetrical on both sides – have the effect that the powder vapors escaping laterally do not participate in the effect of the additional recoil caused by the gases escaping to the front.

Rear-facing holes or slots are efficient in reducing recoil. They are more effective the more rearward they are directed. The shooter will see the same thing when hot gases blow around his ears. In Swiss military weapons, the Best 300 Blackout Muzzle Brakes are provided with holes or slots distributed all around. The soldier lying in dry sand or dust will literally “kick up dust” with the downward facing bores.

Muzzle brakes are said to increase the sound of the shot. This is not true. The shot bang perceived by the shooter – behind the barrel muzzle – is perceived as louder the further to the rear the shot gases are deflected. Magnum cartridges are usually equipped with rather inert propellants.

If the barrel is not long enough, part or the rest of the powder burns before the muzzle. There is suddenly much more combustion-promoting oxygen than inside the barrel. The result is a magnificent fireball. Pistol and revolver shooters appreciate so-called compensators for powerful cartridges. These are holes or slots that allow part of the gas jet to escape upwards and thus efficiently reduce the upward impact of the muzzle.

Influence on the shot bang

As a disadvantage of muzzle brakes, it is repeatedly emphasized that the shot bang is considerably stronger. This may be the case with a gas jet deflected to the rear. Common muzzle brakes with lateral gas outlet holes have also been used in Switzerland for decades in off-duty shooting (Stgw. 57 and Stgw. 90).

I am not aware of any neighboring shooters being disturbed by the gas outlets arranged concentrically around the barrel muzzle. The cases shooting out of the breech on the right side of the assault rifle case are much more unpleasant. It should be noted that what is often repeated does not become any truer. However, theoretically, there is indeed the possibility that Best 300 Blackout Muzzle Brakes make the muzzle blast seem louder under certain conditions.

The interrelationships are quite complicated and defy a simple explanation. Factors that influence this are caliber, size of the holes or slots of the muzzle brake, frequency of the muzzle blast, etc. The phenomenon can be compared to the sound of heavy motorcycles, which are perceived as very loud due to the frequency of their engine noise.

This is due to the fact that the human auditory system perceives low-frequency sounds as significantly louder than the standardized 1000 hertz of the phonics scale.

Who needs a muzzle brake?

Strictly speaking, nobody. There are no game species that have to be hunted with calibers that require muzzle brakes to protect the shooter’s collarbone. Those who hunt in the Grisons, where the minimum caliber is mandatory, will do well with the classic 10.3x60R.

Anyone who shoots 416 Rigby or similar with muzzle velocities of over 900 m/s may well be the beneficiary of a Best 300 Blackout Muzzle Brakes.

Without wishing to offend anyone here, the self-chosen degree of machoism or masochism plays a role, so that one may assume that the shooter of corresponding calibers will do without such facilitations with a smile. Reasonably, one can advise a muzzle brake from a muzzle energy of more than 4000 joules.

This would then already affect the 7×64 and the 10.3x60R. The increase in shooting comfort is considerable. Especially the (many) hunters, who tend to muck, will profit from this. (Sorry, there are many more than you would think. No, I don’t mean you yourself, of course). A 300 Win. Mag. shot with a Best 300 Blackout Muzzle Brakes gives the impression of shooting with a 243 Win. That is – subjectively – about 40% less recoil.

The trend towards short-barreled weapons (tendency towards 50 cm) makes it advisable to use a muzzle brake in strong calibers. Of course, this increases the overall length of the rifle somewhat. Blaser manufactures short barrels on request, the maneuverability of which is extremely practical for hunting.

If desired, the appropriate Best 300 Blackout Muzzle Brakes attachment can also be supplied. Blaser barrels have a reputation for excellent precision, so there is nothing to be said against a short barreled rifle with a muzzle brake. Muzzle brakes are usually only used on rifles. The recoil of shotgun ammunition in cal. 12/70 or 76 does not require such an accessory. On combined weapons, a muzzle brake could (!) not be excluded on the rifle barrel. However, I am not aware of any such weapon at present.
