SureFire SOCOM556 Monster Fast-Attach .223/5.56 Rifle Sound Suppressor


The SOCOM556-MONSTER Fast-Attach® sound suppressor has serrated teeth on the front plate for added bite should the situation demand it, but is otherwise identical to our SOCOM556-RC suppressor, which was recently selected for the M4 and Mk18 carbines by US Special Operations Command after placing first in the most extensive and rigorous suppressor testing ever conducted, and which also received the USSOCOM official safety verification in support of fielding.

The SOCOM556-MONSTER features advanced internal venting to reduce back pressure, reducing the suppressed cyclic rate and gas blowback on the operator. The new design also includes an integrated blast shield in the back section that increases durability. SureFire's patent-pending front-plate design, along with proprietary improvements in gas-flow dynamics, nearly eliminates first-round flash, a technological breakthrough in this area. It also attenuates noise and dust signatures to an unprecedented degree.

A new indexing system means this suppressor mounts to a current-model SureFire muzzle brake or flash hider even more solidly than our previous versions, and is easier to remove after extended firing since the index tab is in a low carbon-buildup area.

Like all SureFire Fast-Attach models, the SOCOM556-MONSTER produces minimal, consistent point-of-impact shift compared with the unsuppressed weapon regardless of the number of attach-detach cycles.

The SOCOM556-MONSTER is constructed from advanced US mill-certified high-temperature alloys and heat-treated stainless steel, and features a tough, corrosion-resistant Ionbond coating on the Fast-Attach® lock ring and Cerakote™ ceramic finish on the suppressor body, in either Black or Dark Earth color.

All SureFire SOCOM Series suppressors require a compatible, latest-model SureFire muzzle brake/adapter or flash hider/adapter for attachment to a firearm. See Parts and Accessories on this page.

SureFire sound suppressors for rifles and machine guns combine every important suppressor feature: excellent sound, flash, and dust signature reduction—key components of SureFire's Total Signature Reduction™ (TSR); minimal and consistent zero shift regardless of attach/detach cycles; rock-solid attachment in seconds; compact size; minimal weight; fail-safe baffles to prevent bullet side-exit; and extreme durability permitting full-time use. In fact, your SureFire suppressor should outlast your firearm barrel, depending on use.

All SureFire Fast-Attach® sound suppressors provide crucial tactical benefits—they reduce the weapon’s sound signature, concealing operator's position and protecting both the operator and team members against both permanent and temporary hearing loss, while enhancing situational awareness and communication; reduce or virtually eliminate muzzle flash, concealing operator's position and preserving night vision and unobstructed view; reduce dust signature, concealing operator’s position and maintaining unobstructed view; and reduce recoil, improving bullet impact observation and allowing for faster follow-up shots.

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

Best of the best! September 6, 2018
Reviewer: 2ASuperfan from USA  
Let me start of by saying I'm a class 3 dealer. I have...let's just say more than the average person. This can has the best sound and tone I've ever heard. Low db rating is good and all but the tone is what really matters. This can has no ring to it what so ever. I did not purchase this for a customer, I got it for my personal collection. If you're on the fence about getting this....do it. You won't be disappointed! Plus the price they are selling these at.......

Awesome prices, fast shipping. January 3, 2018
Reviewer: Mike M from PA United States  
Found the best prices on the highest quality suppressor available. Surefire Suppressors are 100% made of a High temp alloy (except the locking ring) which make them very expensive. The best feature is the little or no zero change with it on or off. Great designed adapters as well.
