If your tool for the job is a short-barrel 5.56 mm (.223 caliber) rifle, you shouldn’t have to compromise on the performance or reliability of your suppressor. With the SureFire SOCOM556-SB2, you don’t have to.

Designed and engineered by the same dedicated team that persevered to earn a SureFire victory in the extremely demanding US Special Operations Command (SOCOM) suppressor trials, the SOCOM556-SB2 delivers extremely low back pressure and stealthy sound attenuation in a suppressor optimized for rifle barrels of 10 inches or less. The SOCOM556-SB2 suppressor weighs a mere 17 ounces and can add as little as 3.8 inches to overall weapon length for easy carry and handling. Its superior high-temperature alloy and stainless steel components are precision CNC laser-welded for strength and durability even when used in full-auto mode. Innovative internal baffling gives the SOCOM556-SB2 a significant decrease in back pressure, cyclic rate and gas blowback, which yields a tremendous reduction in sound and dust signatures with virtually undetectable first-round flash. It matches supreme quiet and stealth in one compact unit.

The SOCOM556-SB2 also features SureFire’s proprietary Fast-Attach® system, which allows for easy and reliable installation or detachment from the weapon in seconds. And like every SureFire Fast-Attach model, you can count on the SOCOM556-SB2 to produce minimal and consistent point-of-impact shift compared to that of an unsuppressed weapon.

Built for consistent performance and a long service life, every SureFire suppressor is proudly designed and manufactured in the USA.

clean silencer immediately

I have had the unfortunate scenario where i couldn't clean my firearm right away. What happens if you don't the carbon build up will case the silencer to get stuck on the flash hider. I guess i have to take a blowtorch to heat it up to get get it off. The other sol;union i have seen is shoot it off and I'm not doing that. Other then this, this is the best silencer on the market for ar platforms. IO often wonder what the military does to combat this.
