The SureFire 5.56mm Training Suppressor (brand part number SF-TRAINER-556-1-BK) is a solid, non-functional trainer built to match the size, weight, and mounting profile of a genuine SureFire suppressor without containing any baffles or sound-reduction components. SureFire builds this piece for armorers, instructors, and departments that need suppressor-shaped hardware for weapon-manipulation drills, holster and case fitting, or photography and display purposes, without the cost, paperwork, or wait time of a real Title II suppressor. Because it contains no baffles and provides no actual sound suppression, it does not meet the legal definition of a firearm silencer and is not regulated under the National Firearms Act. It is a practical training aid for anyone who needs to rehearse mounting, dismounting, and handling a suppressed 5.56mm carbine without owning an actual NFA item.
