Legacy Muzzle Brake / Adapters — 5.56 mm (.223 Caliber)


SureFire Legacy (Prior-Generation) Muzzle Brake / Suppressor Adapters

The muzzle brakes listed on this page are our prior-generation models. They provide the same superior performance as our new SOCOM Series muzzle brakes, but they cannot be used as adapters to attach SOCOM Series sound suppressors to firearms. They can only be used to attach our Legacy (prior-generation) sound suppressors to firearms. If you have questions: suppressorhelp@surefire.com or call us at 800-828-8809.
