The 6 Best 300 Blackout Suppressors

The 6 Best 300 Blackout Suppressors

[lwptoc]

Many enthusiastic gun owners would not be surprised to find out that the repeated blast from a weapon can cause long-term hearing damage. If you have a 300 AAC Blackout weapon, this is where a 300 blackout suppressor comes into play. It reduces the amount of noise (dB) to a fraction of what it would otherwise be, plus it looks incredibly cool to boot.

If you have a firearm that shoots 300 blackout rounds, also known as 300BLK, then it may be frustrating to find the right 300 blackout suppressor that will suit your needs when there is a sea of options available. A good suppressor will be able to decrease the number of decibels (dB) your gun blast creates and make your gun safer in regards to your ear protection

300 blackout suppressors are necessary for an AR15 or similar style rifle in order to protect the ears of the shooter and everyone else on the range. 

When certain military factions needed a better performance from the 5.56×45mm NATO, Remington Defense and AAC developed the 300 BLK to up the ante, and this round type does not disappoint. Many missions still use this kind of round in their full-auto weapons, often with a suppressor or flash hider attached to it. 

A Little Background – Where Did 300 BLK Suppressor Come From?

The power of our rifles seems to get better and better with each innovation, but where exactly did the need to suppress the high power 300 blackout ammunition start?

The AAC developed the 300 blackout cartridge with Remington Defense in response to military systems that needed a little more power than the former-most-well-used option, the 5.56×45mm NATO. They were also looking to replace the midrange performance or the standard 9mm, a pistol round commonly used in SMGs. 

This innovative design worked well to negate many of the issues commonly found with large-caliber cartridges used in the M4. Other companies tried to combat these issues, such as Colt Firearms which made chambered AR-pattern rifles and carbines in many versions of .30 caliber rounds, but this model experienced similar drawbacks. 

If you have a large case head diameter, you may have needed to attach easily defective modified bolts in the days of the past. With the new rounds, you were able to get the power needed without the defects. One problem though, the sound of each round was deafening. 

Thankfully, with modern innovations and multiple teams dedicated to bringing you 300 blackout suppressor designs, you can combat the harmful dB blast that will potentially cause long-term harm to your ears.

Many of the designs featured in our lineup have been since battle-tested and improved upon to bring you only the best options for successfully muting the harmful sound of your firearm blast. 

Whatever the circumstance may be, you will want to invest in a 300 blackout suppressor to ensure the best performance from your rifle while also protecting the longevity of your ear health. Do yourself a favor and check out our top picks for 300 blackout suppressors on the market this year.

Are Silencers Even Legal?

Many people are confused as to how they may attain a 300 blackout suppressor as a civilian multi-caliber rifle shooter. Is it even legal to buy a suppressor for an AR15 that uses 300 BLK rounds?

The short answer: yes. The long answer: well, it depends. Owning a suppressor that follows the rules and regulations of the National Firearms Act (NFA) is currently legal in 42 states. 

If you do not live in one of these states in which it is legal to buy a 300 blackout suppressor, you may want to move to another location before you apply. You must apply for a suppressor with Form 1 with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). You’ll also have to apply for the $200 tax stamp for the NFA item.

We also highly recommend that you create a NFA gun trust for your silencers and other NFA items. The benefits are many, but it is important to note that this will specifically help you with legal security on these items. You can set one up quickly on Gun Trust NFA.  

Filing any paperwork wrong or trying to fill out a form without having the required specifications, may result in a longer delay in receiving your equipment. In order to be able to legally buy a suppressor, you have to be able to legally own a firearm, reside in one of the states in which it is legal, and be at least 21 years of age to buy from a dealer. 

There may be other specifications or requirements that are specific to your district or local government, so be sure to do your research and find the best way to legally buy the 300 blackout suppressor you are searching for.

Some of the states that do not allow the ownership, possession, or manufacture of suppressors are California, New York, Hawaii, New Jersey, and Rhode Island. Do your homework to find out if buying a 300 blackout suppressor is legal in your state, and fill out the proper forms to be able to get your hands on the suppressor you need as soon as possible.
