Sound suppressor

SureFire's Fast-Attach Sound Suppressors for the FA556MG for 5.56 mm machine guns and the FA762K for 7.62 mm rifles and carbines are made of extremely durable high-temperature alloys and stainless steel. CNC machined to exacting tolerances for maximum efficiency and performance, the Fast-Attach feature, allows the suppressor to be attached to or removed from a weapon in seconds. The suppressor design reduces sound levels and muzzle flash of a fired weapon, to help protect the operator's hearing and help keep his location concealed. The SureFire FA556MG Suppressor for 5.56 mm machine guns adds only 5.2 inches to overall weapon length and weighs just 21 ounces.
