The Best Suppressors For .300 Blackout Subsonic Ammo
When the .300 Blackout cartridge came on the scene, it was a game changer for AR platform firearms. You could use the same 5.56/.223 magazines (just be careful not to mix them up) and still get great performance numbers while keeping the decibel level to a minimum.
Oh, and shooting subsonic .300 Blackout through an AR with a suppressor? Man, that’s really quiet – and a ton of fun!
If you’ve never tried it before, just be prepared to be hooked on the combination. If you’ve done it before, well, that’s probably why you’re reading this post. Here are our top picks for suppressors to use with the .300 Blackout cartridge.
The Best .300 Blackout Suppressors
Here are our top four picks for the best .300 Blackout suppressors:
#1: Banish 30
The Banish 30 is a direct-thread suppressor that mounts on conventional 5/8×24 threads and comes out of the box as a 9″ suppressor holding eight baffles.
If, however, you’ll be shooting suppressed in tighter, more confined spaces, or you just don’t want as much can hanging off the end of your barrel, then you’ll benefit greatly from this suppressor’s modularity. It can easily break down and assemble into a 7″ configuration with six baffles. Either way, you’ll still get great sound suppression with minimal added length on your .300 Blackout rifle, carbine, or pistol in either configuration.
Weight is just as important as the overall length in this situation. The Banish 30 is made from a strong titanium alloy for unmatched durability at an extremely light weight. In the full configuration, it weighs 13 ounces; in the short configuration, it weighs just 10 ounces. You’ll be hard-pressed to even feel it on the average .300 Blackout rifle, carbine, or pistol!
When it comes time for cleaning, the Banish 30 easily comes apart from both ends and is ready to be tossed in a tumbler, ultrasonic cleaner, or cleaned manually. Reassembly is a breeze due to the baffles being keyed and indexed for exact alignment.
Why We Like It:
- Modular design to fit specific needs
- User-serviceable for easy cleaning
- Titanium offers great strength with minimal weight
Banish 30 Specs
- Weight: 10 oz or 13 oz
- Length: 7″ or 9″

#2 Dead Air Sandman-S
Dead Air’s Sandman suppressors have great reputations and with good reason. The Sandman-S is the “little brother” to the Sandman-L, and while it may be smaller, it still retains all of the performance. Featuring a low blowback design, the Sandman-S is touted for not only its compact construction but also for its impressive noise reduction at the ear. It does a great job at dropping the decibels of a .300 Blackout cartridge.
The Dead Air Sandman-S features a quick-detach mounting system that incorporates an index pattern for ease of mounting and removal. It’s also outfitted with a removable front-end cap, making the Sandman-S extremely user-serviceable, allowing for quick disassembly, cleaning, and fast reassembly.
Why We Like It:
- QD mounting system for easy on-off
- Great sound reduction for the size

#3: SilencerCo Omega 300
SilencerCo’s Omega 300 is the lightest, shortest, quietest, full-auto-rated, titanium silencer in its category. If you like to have choices and options, it even comes complete with direct thread and fast-attach mounts, as well as a removable Anchor Brake to reduce recoil, which can be replaced with a flat front cap if you don’t need the brake.
The Omega 300 is popular for all sorts of .30-caliber chamberings, including the .300 Blackout cartridge. That makes it one of the best multi-caliber suppressors in its class, so it will be right at home on a variety of other rifles, too. You aren’t just limited to the .300 Blackout, so try it out with .30-06, .308, .300 Blackout, etc.
Why We Like It:
- Multiple mounting options come with it
- Comes with a brake in the box
- Best in class specs in its category

#4: Banish 30 Gold
An exceptionally versatile suppressor, the Banish 30 Gold is rated for calibers from rimfire up to 300 RUM. All Banish suppressors have been designed for unmatched sound suppression, and testing shows that the Banish 30 Gold reduces the report by 36 decibels. The average sound level heard by shooters from the Banish 30 Gold is 132.9 decibels!
Like all Banish suppressors, the Banish 30 Gold is made from a strong titanium alloy that results in unmatched durability at an extremely lightweight of just 13 ounces.
The Banish 30 Gold is an 8.2-inch quick detach suppressor holding 11 baffles, and comes with two 100% titanium muzzle brakes (1/2×28 and 5/8×24). Completely user-serviceable, you can disassemble the suppressor for cleaning in a tumbler, ultrasonic cleaner, or by hand. When you’re ready to put it back together, the baffles are keyed and indexed for a hassle-free reassembly.
Perfect for everything from a fun time at the range to big game hunting, the Banish 30 Gold will significantly reduce the report and recoil of large-caliber rifles (up to 45% in testing), while still being effective on rifles down to rimfire calibers.

Benefits of Using Suppressors
There are a lot of different reasons why you should use a suppressor, but here are three of our favorite benefits that make a suppressor worth it.
Less Noise
As was explained above, suppressors bring down the decibels that you hear each and every time a gun is shot. Making less noise while shooting is beneficial if there are a lot of people at the shooting range if you’re out hunting, or simply if you’re trying to do everything possible to preserve your hearing.
Better Accuracy
An extra benefit of suppressors is that they reduce the felt recoil when a gun is fired. Since there’s less recoil, both you and the gun are moving around less than you would without a silencer. That reduction in movement helps you to make more accurate shots.
More Fun
Shooting suppressed is simply a ton of fun. Seriously, we’ve never met anyone who shot suppressed for the first time and then turned around with a frown on their face. It just makes the entire shooting experience a lot more enjoyable.
