The FA762K sound suppressor, an end-mount design that does not overlap the firearm barrel, adds just 5.6 inches to the original length of your Armalite AR-10, Knight SR-25 Battle Rifle, Bushmaster BAR-10, DPMS LR308, M1A, M14, Mk14 EBR, Springfield Scout, HK 417, or other 7.62 mm / .308 caliber rifle, yet it provides superior sound suppression. The FA762K will also fit bolt-action rifles, such as the Remington 700P, that are threaded to accept a compatible SureFire suppressor adapter. All SureFire sound suppressors require an adapter for attachment to a firearm. Adapters for the FA762K sound suppressor screw directly onto the original rifle muzzle threads-see Parts and Accessories below. Chosen by the US military, SWAT teams, and law enforcement agencies across the country, proven in the world's toughest combat conditions, only 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. All SureFire Fast-Attach® sound suppressors provide crucial tactical benefits-they protect shooter and team members against both permanent and temporary hearing loss, enhancing situational awareness and communication; reduce sound signature, concealing shooter's position; reduce or virtually eliminate muzzle flash and dust signatures, concealing shooter's position, preserving night vision and unobstructed view; reduce recoil, improving bullet impact observation and allowing faster follow-up shots.
