A suppressor system includes at least one inner core having a core bore defined therein, the core bore having a nominal core bore diameter. The inner core also includes a core-coupling portion. A plurality of muzzle brakes that each includes a bore having a nominal brake bore diameter. Each muzzle brake includes a brake-coupling portion. The inner core is configured to allow the brake-coupling portions of muzzle brakes having nominal brake bore diameters that are equal to or less than the nominal core bore diameter to couple to the core-coupling portion and to prevent the brake-coupling portions of muzzle brakes having nominal brake diameters that are greater than the nominal core diameter from coupling to the core-coupling portion.
