In testing

I have recently purchase and installed this muzzle brake on my rifle build. At first it was kind of annoying trying to figure out which crush washer I needed, but after I found the right one it was very easy to install. Took me less than 20 minutes. I have not used the rock set yet, because I haven't had the chance to shoot the rifle with this on. I am hoping to test it this weekend. That's the only reason I gave 3 stars for reliability, durability, and product performance. I am confident that I'll be happy with it, but I can't say until I actually test the product.

Best On The Market!

This is truly the best performing quality made muzzle brake on the market! Takes little to no time to install correctly and does exactly what it says it does! For the money, you can't go wrong with the Surefire sfmb-556-1\2-28 muzzle brake! My Colt M4 thanks you for the quality!

surefire brake

Excellent product with excellent instructions. Great fit just takes some time to clock it correctly. Will buy one for my 30-06 700 remington build.

Something not right

This was the brake I was told by Surefire fit my gun and suppressor. Brake installed well on my SIG. Suppressor mounted tight. First shot blew the suppressor off the end off my gun. Suppressor had a bullet hole at 4 o'clock position a muzzle of suppressor. Between brake and suppressor $1,800,00 down the tube.

Great product

Got this for my personal AR build. Night and day difference between the Surefire and the standard Colt Muzzle Break.
Follow up shots are very quick and tight. I would recommend this muzzle break to anyone.

Quality product from a quality company

I bought this muzzle brake for an ar15 I built. Have only shot about two mags with it but I gotta say so far I love it. I plan to do more extensive shooting from various positions to see how it really helps. I also bought this muzzle break to test on my ar15 because I buy another for my armalite ar10 supersass. Needless to say I will be ordering another. Love it!

Precision made, outstanding performance

I use my Surefire 556 suppressor on several rifles from 17 HMR to .223//5.56 All the mounts/adapters have been flawless with the QD system. Best of all, the performance of the suppressor is every bit as good as the fit of the mounts. I recommend them highly.

Description

SFMB-556-1/2-28
The advanced SureFire SFMB-556-1/2-28 muzzle brake, which fits M4 / M16 weapons and variants with 1/2-28 muzzle threads, greatly reduces both recoil impulse and muzzle rise so that the weapon tracks straight back to keep you on target for faster shot-to-shot recovery. Its patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects. The SFMB-556-1/2-28 also serves as a rock-solid mounting adapter for SureFire SOCOM Series 5.56 mm Fast-Attach® suppressors, the SOCOM556-RC model having placed first in the most extensive and rigorous suppressor testing ever conducted by US Special Operations Command.

Precision machined from US mill-certified heat-treated stainless steel bar stock—including high-precision single-point cut threads for optimum thread interface—the SFMB-556-1/2-28 muzzle brake is given a black Ionbond DLC coating to provide maximum protection under harsh environmental conditions and to facilitate cleaning even after extreme use.

When used in conjunction with a SOCOM Series suppressor, the patent-pending design of the SFMB-556-1/2-28 provides multiple bearing surfaces to ensure superior suppressor alignment. A rear labyrinth seal minimizes potential carbon buildup in the indexing system and facilitates suppressor removal after extended firing.

All SureFire SOCOM Series muzzle brakes have blind pilot holes at the 3 and 9 o’clock position to enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. They also have blind pilot holes at the 6 o’clock position to enable indexing the adapter at bottom dead center, and to pin-and-weld on short-barreled rifles. All that is required is a basic hand drill and appropriate drill bits.

SureFire muzzle brakes are individually inspected for concentricity and alignment, and each is covered by SureFire’s No-Hassle Guarantee.

FITS: M4, M16 and variants wih 1/2-28 muzzle threads

MOUNTS: All SureFire SOCOM Series 5.56mm/.223 caliber sound suppressors

NOTE: SureFire SOCOM Series Fast-Attach sound suppressors and current-model muzzle brake/suppressor adapters and flash hider/suppressor adapters are not compatible with previous SureFire Fast-Attach sound suppressors, muzzle brakes, or flash hiders.
