Harley Flanagan, who co-founded the Cro-Mags, reached a settlement in April 2019 with former singer John Joseph and former drummer Mackie Jayson.

One Cro-Mags lineup from this time consisted of Flanagan on drums, Mayhew on guitar, Todd Youth on bass and Casanova on vocals.

[7] Youth briefly rejoined the band after Miret's departure, at the same time Robb "Nunzio" Ortiz joined as an additional guitarist.

[9] Following this, they would go on hiatus as Flanagan went to California then Canada, during which time he wrote and recorded demos for the songs "Everybody's Gonna Die", "Don't Tread On Me", "By Myself" and "Do Unto Others".

He then recruited Eric Casanova on vocals, before meeting Parris Mayhew in 1983, who then joined as guitarist, along with drummer Mackie Jayson.

[7] Joseph parted ways with the band again after The Age of Quarrel, leaving Flanagan to sing on the second Cro-Mags album, Best Wishes (1989), which had a more heavy metal-influenced sound.

In 2008, John Joseph and Jayson began playing shows under the Cro-Mags name with other established hardcore musicians such as Craig Setari from Sick of It All on bass and A.J.

In 2018, Flanagan filed a federal trademark infringement suit against John Joseph and Mackie Jayson in the Southern District of New York.

On June 28, 2019, the Cro-Mags released their first new music in nineteen years, while heading into a 5-show run with the Misfits[16] sharing three new songs "Don't Give In", "Drag You Under", and "No One's Victim",[17] and toured in North America and Europe.

[20] On March 31, 2020, the band offered a free download of the track, "The Final Test" and announced the June 19 release date of their first studio album in twenty years, In the Beginning.

The groups billed themselves as Cro-Mag Jam, Street Justice, Age of Quarrel, FVK (Fearless Vampire Killers) or Cholo-Mags.
