Thunder Beast Arms CB Muzzle Brake, 30CB, 9/16×24

The CB-series Muzzle Brake is a mount for all TBAC Compact Brake (œCB) series suppressors, including the 223CB, 30CB5, 30CB7, and 30CB9.

When used alone, the new œCB brake is approximately 30-40% more effective at recoil reduction than the old 30BA brake. This new brake is proportioned correctly for .223 and .30 caliber rifles, but it provides a suppressor mounting surface just as solid as the old BA series.
