300 Blackout isn’t a tremendously aggressively recoiling round. But a muzzle brake makes your rifle easier to shoot, regardless of what caliber you’re blasting with.
There’s another benefit to using a 300 Blackout muzzle brake, though: many muzzle brakes also serve as suppressor mounts.
300 Blackout is one of the best rounds for a suppressor host. So having suppressor mounting capabilities is especially relevant for 300 Blackout rifles.
What’s the best 300 Blackout muzzle brake, you ask? We did a little digging to find out.
SPOILER—if you just want to know what we found, get the VG6 Precision Gamma 300BLK Muzzle Device. It’s built specifically for shooting 300 Blackout. The recoil reduction is excellent. And the muzzle blast won’t quite blow anyone’s face off.

Read the reviews that you can afford.
1. VG6 Precision Gamma 300BLK Muzzle Device - Overall Best 300 Blackout Muzzle Brakes
The VG6 Precision Gamma 300BLK Muzzle Device is one of my favorite muzzle brakes for any caliber. But it’s especially nice on a 300 Blackout rifle.
Because the recoil reduction is excellent. And the muzzle blast is reasonable.
Now, there are muzzle brakes that offer better recoil reduction. But the recoil reduction isn’t that much better. And you get significantly more muzzle blast from better performing muzzle brakes.
This muzzle brake seems to be in the sweet spot between ridiculous muzzle blast and recoil reduction.
Additionally, this muzzle brake looks rad. The aesthetic is nice. But it’s not over the top. Though, this is subjective.
What’s not subjective is that the finish on this muzzle brake is super nice. It’s a black nitride coating with a satin finish.
The black nitride offers good corrosion resistance. And the satin finish matches most barrels and handguards.
Also, if you need a slightly longer muzzle device to get your barrel to 16 inches, the VG6 Precision AR .308 Gamma 762 Muzzle Brake is long enough to pin and weld to a 14.5 inch barrel for compliance. And it’s the same muzzle brake design, with an extra port.
This muzzle brake also works as a compensator to help keep your muzzle level. And the solid bottom side helps reduce your dust signature when you’re shooting from the prone.
The only downside to this muzzle brake is that it’s a dedicated muzzle brake. There are no suppressor mounts.
But, if you’re not interested in suppressing your rifle, and you just want something that shoots really soft and flat, this muzzle brake is the way to go.
2. VG6 Precision AR 308 Epsilon 762 Muzzle Brake - Budget 300 Blackout Muzzle Brake
The VG6 Precision AR 308 Epsilon 762 Muzzle Brake delivers some of the best recoil reduction per dollar on the market.
The VG6 Gamma is one of the best muzzle brakes on the market. And this muzzle brake actually performs even better.
It’s a 3-port muzzle brake with compensation ports. So it helps your rifle shoot softer and flatter. You get exceptional control for fast, precise shooting with this muzzle brake.
It’s also long enough to bring a 14.5, and maybe even a 13.9 inch barrel within compliance to save you money on an SBR tax stamp if you don’t want to pay for one.
The black nitride satin finish looks great on most rifles. And the finish resists blast corrosion very well.
However, this muzzle brake produces mind blowing muzzle blast.
If you intend to use your rifle as a home defense gun, this may not be the best muzzle brake. Without hearing protection (inside a house, at that), the muzzle blast is going to blow your face off. It’s serious.
Also, this muzzle brake has no suppressor compatibility. So you have to deal with the muzzle blast.
But, if your primary goal is recoil reduction for competition or recreational shooting, this muzzle brake is the most affordable option.
3. SilencerCo Harvester Big Bore Muzzle Brakes - Suppressor Compatible 300 Blackout Muzzle Brake
SilencerCo makes some of the best suppressors on the market. The SilencerCo Harvester Big Bore Muzzle Brakes gives you compatibility with almost all of the SilencerCo suppressors. And it’s a decent muzzle brake.
This is a 3-port muzzle brake. It delivers solid recoil reduction.
Now, you don’t get quite as much recoil reduction as you get from some dedicated muzzle brakes. But the recoil reduction is respectable. You could easily use this muzzle brake on a competition rifle or something similar.
However, there are no compensation ports. So the rest of your rifle will be responsible for keeping your muzzle flat.
On the bright side, the muzzle blast is fairly minimal, for a muzzle brake. It’s still a muzzle brake. And it’s definitely not pleasant if you’re standing next to it. But the muzzle blast is totally bearable.
Another good thing: this muzzle brake is long enough to get a 14.5 inch barrel to 16 inches.
And this muzzle brake is also an ASR suppressor mount for SilencerCo suppressors. So you can dodge the muzzle blast by adding a suppressor.
This SilencerCo muzzle device isn’t intended to be a perfect muzzle brake.
However, it’s a good muzzle brake. And it enables you to suppress your 300 Blackout rifle with some of the best suppressors on the market.
One more thing: if you prefer Dead Air Armament suppressors, you can get the Dead Air 7.62 Muzzle Brake. It’s very similar. But it includes compensation ports and has KeyMod suppressor compatibility.
4. Phase 5 Weapon Systems Inc. Littleboy Hex Brake - SBR 300 Blackout Muzzle Brake
If you have a 300 Blackout SBR, you probably intend to use it as a suppressor host. However, if you’re not going to suppress your SBR, the Phase 5 Weapon Systems Inc. Littleboy Hex Brake is a great option.
As a muzzle brake, this one works very well. The recoil reduction is solid. You’ll get a noticeably softer recoil impulse with this muzzle brake.
This muzzle brake also has compensation ports to help keep your muzzle flat. That helps you get faster follow-up shots.
But, the thing that makes this a good option for a 300 Blackout SBR is the muzzle blast. It’s not too bad, in general.
But this muzzle brake also does a great job of directing that muzzle blast away from the shooter. That’s important when the muzzle is closer to your face. This muzzle device is as comfortable as a muzzle brake can be for you and the people around you.
Also, you can get the Phase 5 Weapon Systems Inc Fatman HexBrake if you don’t want your rifle to be an SBR. This is the same muzzle brake, it’s just longer, which is handy for pinning and welding.
My only complaint about this muzzle brake is the parkerized finish. It’s a decent finish that gets used on a lot of AR-15 components. But it doesn’t resist corrosion as well as some other finishes.
The finish works well enough, though. And this Phase 5 Weapon Systems Inc model is one of the most comfortable muzzle brakes that you can get, which is ideal when your muzzle is closer to your face.
5. Precision Armament AR .308 M4-72 Severe-Duty Brake 30 Caliber - 300 Blackout Muzzle Brake for Recoil Reduction
If the only thing that you care about is recoil reduction, the Precision Armament AR .308 M4-72 Severe-Duty Brake 30 Caliber is the muzzle brake for you.
It’s been tested. And this muzzle brake offers some of the best (if not THE BEST) recoil reduction on the market. It makes your rifle super comfortable to shoot.
However, the muzzle blast is also one of the strongest on the market. It’s severe enough that you’ll need your eye protection to shoot your rifle. But, hey, the recoil will be super soft.
Also, this muzzle brake doesn’t have any compensation ports. But the vents are angled upward. And the recoil reduction is solid enough that this muzzle brake definitely helps keep your muzzle flat in rapid fire.
It’s not all about performance, either. This muzzle brake is also super durable. It’s machined from stainless steel. And the finish is remarkably corrosion resistant. This muzzle brake will last for a super long time.
Lastly, this Precision Armament model is long enough to make a 14.5 inch barrel compliant.
Ultimately, this review comes back to the original statement: this is an amazing muzzle brake to get if all you care about is recoil reduction.
6. Lantac Dragon Muzzle Brake - Suppressor Compatible 300 Blackout Muzzle Brake
The Lantac Dragon Muzzle Brake is a really solid muzzle brake in its own right. However, it also comes with suppressor compatibility for 3 of the most popular suppressor manufacturers:
- LANTAC Dragon Muzzle Brake with Dead Air KEYMO Suppressor Mounts.
- LANTAC Dragon SilencerCo ASR .308/7.62 Muzzle Brake.
- LANTAC Dragon GemTech Quick Mount .308/7.62 Muzzle Brake.
So you can get this muzzle brake for whatever type of shooting you want to do and with compatibility for a whole lot of suppressors.
But that’s not all.
This muzzle brake also offers impressive recoil reduction. It’s actually a bit better than the muzzle brakes from SilencerCo and Dead Air Armament.
And, unlike the SilencerCo muzzle brake, this muzzle brake has compensation ports that really help keep your muzzle flat in rapid fire.
Some shooters find that the compensation ports actually drive their muzzle down if they shoot fast enough.
Additionally, this muzzle brake is more stylishly designed than the muzzle brakes from SilencerCo, Dead Air Armament, and GemTech. It looks great (and looking cool matters).
Additionally, the finish is outstanding. It looks like a black nitride finish.
However, it seems more durable than most black nitride finishes. It resists corrosion and carbon buildup impressively well, which is very nice since the muzzle brake works as a sacrificial baffle when you mount a suppressor.
Unfortunately, this Lantac muzzle brake is a tad expensive. But, the performance is good enough that the price is totally justified. And it comes with suppressor compatibility to boot.
Slamming the Brakes!
300 Blackout is an excellent round. But, it’s a tad fatter than 5.56mm. And, if a muzzle brake makes sense on a 5.56mm, a muzzle brake makes sense on a 300 Blackout rifle.
Also, since muzzle brakes often double as suppressor mounts, a muzzle brake can be even better on a 300 Blackout rifle, because 300BLK makes a great suppressor host.
Want a great muzzle brake that’s surprisingly affordable, given the performance? Get the VG6 Precision Gamma 300BLK Muzzle Device. It’s easily the most recoil reduction per dollar that you can get.
It’s time to stop waffling. Get a muzzle brake and make your 300 Blackout rifle more comfortable to shoot.
