This is a new Surefire SOCOM 556-Mini-Monster silencer. It is flat dark earth in color, has a quick detach lock-ring, and has serrated teeth on the front plate. This silencer features a solid attachment in seconds, a compact size, minimal weight, fail safe baffles to prevent bullet side exit, and extreme durability permitting full time use. The Total Signature Reduction system features excellent sound, flash, and dust signature reduction. All SureFire SOCOM Series suppressors require a compatible, latest-model SureFire muzzle brake/adapter or flash hider/adapter for attachment to a firearm. SureFire states that your SureFire suppressor should outlast your firearm barrel, depending on use. All NFA rules apply.
