Best Suppressor for 300 Blackout

Since its standardization in 2009, the 300 Blackout round has been a favorite for suppressor enthusiasts, myself included. The 300BLK is designed to be fired either supersonic or subsonic, which is what makes it such a great choice for use with a silencer. Shooting subsonic suppressed 300BLK is wildly quiet and has nearly no recoil, but delivers more energy than pistol rounds, which has led to its popularity with tactical shooters, hunters, and for showing off how quiet your gun is at the range. 

300 Blackout really shines with a silencer, the round was developed with the intention of being shot suppressed. And while any .30 caliber will work with 300BLK, we have decided to figure out which silencers were best for the job.

Shooting 300 blackout suppressed is some of the most fun you can while shooting, the lack of noise, concussion, flash, and recoil is sure to put a smile on your face. Getting a suppressor for your 300BLK takes it to the next level, and we’ve had the opportunity to shoot all of the best 300 Blackout suppressors available and have built a list to help you choose which suppressor is right for you! 

The engineers who designed the 300 AAC Blackout cartridge are the same people who designed the Trash Panda, and this silencer was built specifically to work with 300BLK. The Trash Panda is made of titanium, so it keeps your compact 300 Blackout lightweight and maneuverable and is compact at just under 7” long. The Q Trash Panda was one of the first silencers to use a 1.75” diameter to get extra volume without adding length, and that extra diameter translates to lower decibels, especially when shoot subsonic rounds.

And, if you need the absolute quietest shot experience, you can step up to the Q Thunder Chicken, which is identical to the Trash Panda, just a little longer for extra sound reduction making it one of the quietest 300 blackout suppressors.  

The Dead Air Nomad has been a go-to 30-caliber suppressor for a few years now due to its versatility and sound performance across a variety of calibers, but it really excels on subsonic suppressed 300 BLK. That excellent sound performance is due to its two-chamber coaxial baffle design paired with its large diameter; that combination allows the Dead Air Nomad to shine on the low-pressure 300BLK round.  

At 6.5” long it will keep your loadout compact and weighs just 14.5 oz but is extremely robust thanks to its steel construction. That durable tubeless steel design also means the Nomad is full auto rated, if you’re lucky enough to have access to a machine gun. The Nomad also has a longer option, the Nomad L, if you want even more decibel reduction.  

My favorite part is how customizable this suppressor is, and it cements it as one of the best 300 blackout suppressors. On the mounting end, it features a HUB mount, so you can swap out the included direct thread of any quick detach (QD) system you want. On the muzzle end, it uses the Dead Air R-Series endcaps, so you can swap it out with caliber-specific options, external brakes, or flash hiders to build this suppressor exactly how you want it.

The Hyperion from CGS had one goal when it was released, be as quiet as possible. It accomplished that goal by using a 3D printed design to create intricate baffle structures that efficiently traps an enormous amount of gas, which results in a whisper quiet shooting experience. The Hyperion is 9.5” long and 1.5” in diameter, it uses all of that size to condense the sharp “BANG!” of a gunshot down to a soft “pew” that will make you grin.  

The Hyperion can pull double-duty, if you do plan to shoot other calibers this silencer can handle up to 300 RUM, even those high pressure rounds sound great through this suppressor.  

The 300BLK is made to run in an AR15 platform and the HUXWRX FLOW series is made to suppress AR-style rifles, it’s a great match. The HUXWRX FLOW762 Ti is a 3D printed Flow Through suppressor, instead of gas getting blown back into your guns action, it vents through the suppressor and down range. That is particularly important for AR’s as reducing the gas leads to less port noise, a softer shooting gun, and no gas in your face. The FLOW 762 Ti’s intricate geometry does a fantastic job of reducing sound and backpressure, and is surprisingly light at under 12 oz. The FLOW 762 Ti also works great on high pressure rounds, so if you have a 5.56 AR, AR10, or AK, this gets you even more versatility.

SilencerCo designed the Scythe-Ti for use on hunting rifles, they wanted it to mitigate recoil, drastically reduce sound, and be so light that you’ll hardly notice it; those features make it an incredible option for 300BLK rifles. The Scythe is the lightest silencer on this list at just 7.3 oz, it will keep your 300BLK SBR maneuverable and nimble. And to match your 300 BLK, the Scythe-Ti BLK is exclusive to Silencer Shop!  

 
The Scythe virtually eliminates any recoil with its anchor brake endcap, it is amazing how easily you can stay on target even when shooting quickly, your sites barely move. It also sounds awesome; it uses a large diameter and updated baffle design which helps it drive down decibels on 300 BLK.

CAT ODB 

The CAT ODB debuted in 2024 and quickly became a customer favorite. The CAT ODB is a high performing 3D printed suppressor designed for use on 30cal semi-auto rifles, making it great for 300 Blackout. The ODB achieves amazing signature reduction while also having minimal effects on weapon operation. CATs SURGE BYASS tech is designed to drastically reduce noise and flash without significantly impacting bolt speed, resulting in a reliable system that sounds great and functions perfectly.

300BLK was originally designed around a 9” barrel, but advancements in materials, ballistics, and gun powders have allowed barrles as short at " become more prevalent.

300 Blackout is one of the best calibers to suppress, it is quiet, low recoil, and produces more energy than 9mm. 

The Q Trash Panda is the best all-around Q suppressor for 300 Blackout, and the Q Thunder Chicken is the quietest suppressor for 300 Blackout in the Q lineup.
