Here’s A Quick Look of Our 7 Best 300 Blackout Suppressors

What a Gun Suppressor Actually Is

Blackout Suppressor

A gun suppressor, also often referred to as a silencer or sound modifier, doesn’t actually cancel out the noise your gun makes upon firing, but it does reduce the acoustic intensity of the muzzle report. It also eliminates muzzle flash, and can reduce the recoil of the shot by modulating the speed and pressure of the gas ejection. This can make firing your weapon much more enjoyable, especially when spending a long day on the range. 

Suppressor Legality

There are quite a few misconceptions and questions surrounding suppressor legality, namely due to their regulation under the 1934 National Firearms Act. During this time they were outlawed due to a rise in organized crime concerns, as well as the assumption poachers were silencing their weapons during the Depression-era food shortages and killing livestock for survival; however these claims have long been debunked as a good reason for the law. 

Currently, there are 42 states that allow the use of suppressors, 40 of which have approved them for hunting. However, it is not easy to aquire suppressors, and you are required to pass the ATF background check. For the majority of people this is not an issue, but is a pain in the rear as it can take up to 9 months for approval. Many people fill out the form in advance if they anticipate a future purchase. Online forms may take much shorter, and if you have questions it is best to speak directly to a licensed firearm dealer who can help you with the process. 

How Suppressors Work

Silencers don’t actually ‘silence’ your weapon, hence why the more accepted name, suppressor, is more accurate. Rather they muffle the sound to a more acceptable, and less painful, decibel level. Created by the same guy who invented car mufflers to muffle the sound of the vehicle, these are simple accessories that screw onto the end of your barrel to create the same effect. 

This is achieved through the series of chambers that exist within the silencer. As the gases pass through these chambers, they are cooled and dissipated before they leave the barrel. This lowers the sound produced when you fire your gun significantly, making it much more bearable to an unprotected ear. 

Benefits of Using Suppressors

There are quite a few benefits to consider from the use of a suppressor, and the most important surrounds safety. The threshold for sound safety is approximately 140 decibels according to OSHA. To put this into perspective, normal conversation falls somewhere around 65 decibels, and the sound of a cap gun is 155 decibels. Rifles and shotguns fall above this range, and can be damaging to the unprotected ear. 

Sound Reduction

A silenced reduces the decibel range by 14 to 45 decibels depending on the choice you prefer, the type of load you are using, and the firearm. This is a significant reduction, especially when combined with ear protection. It also makes anyone nearby much more comfortable, including neighbors that may be close to where you regularly shoot. 


On that note, it also helps reduce noise complaints during hunting season. Not everyone who lives in the country recognizes the sound of a firearm, and often makes honest mistakes in reporting the sound of a gunshot without understanding the laws. Even if you feel they should inform themselves, a silencer can help avoid wasting the time of local law enforcement and the time it takes out of your hunt. 


You also may experience enhanced accuracy due to the reduction of recoil. Most people shoot better with a lighter recoil, especially when shooting multiple magazines worth of ammunition. It may alter your groupings when compared to when you are not using one, but is not less accurate overall. 

What to Consider When Buying a Suppressor

If you are new to silencers you may want to consider a few details prior to purchase. Although most gun manufacturers take great pride in their products, you should always be aware of what you are putting your money down on. 

Material Quality

When looking for the best suppressor quality for the money, take into account the materials being used. Titanium and stainless steel are amongst the toughest choices to consider. Some may have protective coatings as well. 

Ammunition Considerations

Be sure your suppressor is rated for the type of round you plan on using. Subsonic ammunition is more widely accepted than supersonic, so if you are going to shoot both, be sure to look for the proper silencer rated for both. 

Noise Reduction Range

Be sure to look for the noise reduction range that will suppress your weapon below 140 decibels. This means you may need to closely look at the specs of your gun, or run a trial of decibel measurement on your own for accuracy. 

How to Install

Although fairly universal, silencers typically screw onto the end of your barrel with very little effort. Always be sure the threading size of your barrel matches the size of the suppressor you prefer. Quick attach mounts also exist if you like to swap out options to other guns on a regular basis.
