300 Blackout Shooting Performance

The 300 Blackout isn't a round that recoils aggressively. Anyone from young to old will tell you that it's fairly easy to shoot. However, a muzzle brake can make your rifle easier to shoot by redirecting gas at the muzzle in such manner to minimize the muzzle movement, regardless of the caliber you're using. Another benefit of using a 300 Blackout muzzle brake is that many muzzle brakes also function as suppressor mounts.

The 300 Blackout is one of the best rounds for a suppressor host, so having suppressor mounting capabilities is particularly relevant for 300 Blackout rifles.

Note: Muzzle brake featuring 5/8X24 thread pitch is for 308 / 7.62 caliber barrels.

Best 300 Blackout Muzzle Brake

Surefire LR308 - Best Overall

surefire lr308 muzzle brake

I've found the Surefire LR308 to be an incredibly popular muzzle brake choice. One of its standout features is its ability to accept Surefire suppressors without requiring a swap of the muzzle device. This versatility is a real plus.

Designed for 7.62 size bullets, it's worth noting that it's also compatible with the 300 Blackout caliber.

The way this muzzle brake handles gas is impressive. It expels gas both to the left and right, effectively reducing muzzle movement during shooting. Additionally, the top two ports direct the gas downward, which helps keep the muzzle down when the gas exits.

For indoor shooting scenarios. You can attach the Surefire QD Warden Muzzle Blast, which helps minimize side concussion. I find it useful because shooting indoor with a muzzle brake is too disruptive to users next to me, and I don't want that much attention. So the Blast Warden makes shooting next to someone else far less disruptive and more comfortable for everyone involved. It's a thoughtful addition for indoor shooting situations.

SilencerCo Harvester - Best For Suppressor Use

SilencerCo Harvester muzzle brake

SilencerCo makes some of the best suppressors on the market. The SilencerCo Harvester Big Bore Muzzle Brakes give you compatibility with almost all of the SilencerCo suppressors, and it's a decent muzzle brake.

This is a 3-port muzzle brake that delivers solid recoil reduction. 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.

VG6 Precision Gamma 300BLK Muzzle Device

There are muzzle brakes that offer better recoil reduction than the VG6 Precision Gamma, but the difference isn't that much significant (Based on shooters), and you get a lot more muzzle blast from better-performing muzzle brakes.

The VG6 Precision Gamma muzzle brake strikes the perfect balance between minimizing muzzle blast and reducing recoil. Plus, it looks great. The aesthetic is pleasing but not over the top, although this is subjective. What's not subjective is the high-quality finish on this muzzle brake. It's a black nitride coating with a satin finish, which offers good corrosion resistance and matches most barrels and handguards.

The solid bottom side reduces your dust signature when you're shooting from the prone position. The only downside is that it's a dedicated muzzle brake and doesn't have suppressor mounts.

VG6 Precision AR 308 Epsilon 762 Muzzle Brake

The VG6 Precision AR 308 Epsilon 762 Muzzle Brake offers some of the best recoil reduction per dollar on the market. 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.

However, this muzzle brake produces a significant muzzle blast. If you plan to use your rifle as a home defense gun, this may not be the best muzzle brake. Without hearing protection (especially inside a house), the muzzle blast is going to be intense. Also, this muzzle brake has no suppressor compatibility, so you have to deal with the muzzle blast.
