The Rapid Thread Muzzle Brake Blast Diverter is a must-have for AR rifles with Wilson Combat Rapid Thread Muzzle Brakes and Whisper Suppressor attachments. This convenient accessory screws onto the brake’s external threads, redirecting muzzle noise and blast away from both you as the shooter and anyone nearby. Crafted out of robust Melonited carbon steel, this diverter will continue to stand up to heavy use over time.
