Legacy Muzzle Brakes / Suppressor Adapters

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 muzzle brake performance as our new SOCOM Series muzzle brakes, but 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: or call us at 800-828-8809.
