The CMMG Zeroed Muzzle Brake 5.56 is a recoil-taming accessory built to help AR-15 shooters stay on target through rapid follow-up shots. If you're running semi-auto practice drills, hunting, or chasing distance at the range, muzzle rise eats into your accuracy window. This brake uses angled ports to dump recoil energy downrange rather than into your shoulder and sight picture, so you recover faster and shoot tighter groups without fighting the gun.
Built from 4140 steel and coated in nitride finish, the CMMG Zeroed Muzzle Brake handles the abuse of centerfire shooting without compromise. Nitride is famously tough against corrosion and wear, which matters if you're running suppressed loads, shooting in wet conditions, or just want a brake that'll outlast your barrel. The 1/2x28 thread pattern is standard for 5.56 and most .223 barrels, making this a direct swap on most modern AR-15 uppers.
Installation is straightforward: thread it on, seat the included crush washer, and torque to spec. The angled-port design doesn't just push back—it also helps mitigate muzzle rise, so your sight stays closer to your point of aim between shots. That's the real advantage in a fighting rifle or a rapid-fire match stage. Not a suppressor, but it'll make your gun noticeably more manageable than an open muzzle.
| Caliber | 5.56mm |
| Thread Pattern | 1/2x28 |
| Material | 4140 Steel |
| Finish | Nitride |
| Included | Muzzle brake, crush washer |
The CMMG Zeroed uses 1/2x28 threads, the standard for most 5.56 AR-15 barrels. If your barrel is threaded 1/2x28, this will fit. If your upper uses a different thread pitch (like .578x28 on some precision builds), you'll need a different brake.
Yes. The package includes the muzzle brake and a crush washer. You'll need a wrench and possibly a torque wrench to install it properly, but no additional adapters or parts are required if your barrel is already threaded 1/2x28.
A muzzle brake reduces recoil and helps manage recoil-induced muzzle rise, but it does not reduce sound. A suppressor quiets the shot. Many shooters run a brake for speed and feedback; others prefer a suppressor for hearing safety. They serve different purposes.
Nitride is a surface hardening process that makes steel more resistant to corrosion, wear, and rust. On a muzzle brake that sees frequent shooting and exposure to the elements, nitride adds years of reliable service without the maintenance demands of raw steel.
