SureFire SFMB: Recoil Reduction & Suppressor Mount
- Large, Precisely Angled Ports Greatly Reduce Recoil: The SFMB by SureFire features large, angled ports that are designed to redirect a significant amount of the propellant gases to the sides, creating a forward-pushing force that directly counteracts the rearward recoil of the firearm.
- Minimize Side Blast and Rear-Directed Concussion: While no muzzle brake can completely eliminate side blast and rear-directed concussion, the Impulse Diffusion™ Technology makes it more manageable for the shooter.
- Tracks Straight Back: Many users note that the SOCOM Muzzle Brake makes the rifle track "straight back" with very little muzzle rise or "flip", allowing them to get back on target for follow-up shots much faster.

SureFire SOCOM Muzzle Brake Review
What are some common accessories to add to the SureFire SOCOM Brake?
- SureFire SOCOM Series Suppressor: This muzzle brake is designed to work with all SureFire SOCOM series suppressors. The suppressor adds to the overall quiet and flash reduction of your rifle.
- Suppressor Cover: A suppressor cover helps manage the extreme heat generated during use. It protects you from burns and prevents heat from creating a mirage effect in your optic's sight picture.
- Gun Cleaning Kit: Regular cleaning is essential for proper function and maintenance. A good quality cleaning kit will help keep your 5.56 muzzle brake or 7.62 muzzle brake and rifle in top working condition.
- Gun Oil: Lubrication is key for any firearm. Applying quality gun oil to your rifle's moving parts reduces friction and wear.

SFMB Features and Specs
The SureFire SOCOM Muzzle Brake is engineered to manage muzzle movement and prepare your rifle for suppressor use. It uses a patented Impulse Diffusion design to redirect gas and minimize the concussion blast, all while serving as a robust mounting point for SureFire's SOCOM suppressors. Its robust construction and protective coating ensure it can withstand the harshest conditions.
Key Features
- Improved Recoil Control for Faster Follow-up Shots: A dramatic reduction in felt recoil and muzzle rise helps you quickly re-acquire your target for better shot placement.
- Low Concussion Signature for Improved Shooting Comfort: The Impulse Diffusion design redirects gas forward. This reduces the side blast and rear-directed concussion, making the shooting experience more comfortable for everyone nearby.
- Reliable Suppressor Mount for All SOCOM Suppressors: This muzzle brake provides a solid and repeatable mounting platform for all SureFire SOCOM Series Fast-Attach suppressors.
- Easy Suppressor Removal: A rear labyrinth seal prevents carbon buildup. This keeps the suppressor lock ring clean, allowing for effortless attachment and detachment.
- Made in the USA and Built to Last: Precision-machined in the USA from heat-treated stainless steel with a tough Ionbond DLC coating. It stands up to harsh use and protects against corrosion.

SOCOM Muzzle Brake FAQs
What is the primary function of the SureFire SOCOM Muzzle Brake?
The main function is to reduce the recoil and muzzle rise of your rifle. This helps you stay on target for faster and more accurate follow-up shots. It also acts as a secure mounting point for SureFire's line of SOCOM suppressors.
Is this muzzle brake compatible with all SureFire suppressors?
No, the SureFire SOCOM Muzzle Brake is designed to work exclusively with SureFire SOCOM Series Fast-Attach suppressors. It will not fit previous non-SOCOM models.
Is the SFMB Compatible with HUB Suppressors?
Yes, but with an adapter. To make a HUB-compatible suppressor work with the SureFire SOCOM muzzle brake , you need a SureFire Fast-Attach Hub adapter.
What calibers is this muzzle brake available for?
It is available in multiple calibers, including 5.56mm, 7.62mm, 6.8mm, and .338 LM. Each caliber has the correct thread pitch for various rifle platforms.
- SureFire SOCOM Muzzle Brake 556: 223 Caliber (5.56mm) + 1/2-28 Thread Pitch
- SureFire SOCOM Muzzle Brake 308: .308 Caliber (7.62mm) + 5/8-24 Thread Pitch
- .338 Caliber + 5/8-24 Thread Pitch

What is the Impulse Diffusion design?
The Impulse Diffusion design is a patented feature that directs gasses forward and to the sides. This minimizes side blast and rear-directed concussion, making the shooting experience more comfortable.
Can I permanently attach this muzzle brake to my rifle barrel?
Yes, this muzzle brake has pilot holes that can be drilled out for pin-and-welding. This is useful for meeting legal length requirements on short-barreled rifles.
What kind of maintenance does this product require?
Regular cleaning of the muzzle brake and barrel threads is recommended to prevent carbon buildup, especially if you use it with a suppressor.
How do I know which thread pitch I need?
The required thread pitch depends on your rifle's specific barrel. For example, most AR-15 barrels use a 1/2-28 thread pitch, while most AR-10 or 7.62mm rifles use a 5/8-24 thread pitch. Check your rifle's specifications to confirm.
What is the coating on the muzzle brake?
The muzzle brake is finished with a Black Ionbond DLC (Diamond-Like Carbon) coating. This coating is extremely hard and corrosion-resistant, providing long-term durability.
