The Gemtech 13816 5.56 ETM muzzle brake is purpose-built for shooters running Gemtech ETM-equipped suppressors on their AR-15s and other 5.56mm rifles. If you're serious about suppressor use—whether for hearing protection, recoil management, or keeping things quiet at the range—this muzzle device ensures rock-solid alignment and compatibility with your suppressor, eliminating the frustration of misalignment or carbon buildup that can lock a suppressor in place.
At 2.375 inches long and weighing just 2 ounces, this brake is designed to be permanently mounted (pre-dimpled for pin and welding) to a 14.5" barrel, making it a solid choice for rifle builders looking to meet legal length requirements while keeping their setup compact and reliable. The 1/2-28 thread pattern is the standard for 5.56mm rifles and works seamlessly with Gemtech's suppressor line. Black finish matches most modern tactical setups.
This is a no-compromise option if you're building around Gemtech suppressors and want the reliability of factory-matched components. Installation requires a gunsmith for proper pin and weld work—not a job for home assembly.
| Caliber | 5.56mm |
| Thread Pattern | 1/2-28 |
| Length | 2.375 inches |
| Weight | 2 ounces |
| Finish | Black |
| Installation Type | Pin and weld (pre-dimpled) |
This brake is specifically engineered for Gemtech ETM-equipped suppressors. While the 1/2-28 thread is a standard 5.56mm pattern, pairing it with a suppressor from another manufacturer may not provide the same alignment reliability and carbon-lock prevention that this brake was designed for.
This brake requires professional pin-and-weld installation by a gunsmith. The pre-dimpling makes installation precise, but it's a task that demands proper tools and expertise to ensure proper alignment and barrel safety.
This brake is pre-dimpled for permanent mounting to a 14.5" barrel, making it ideal for rifle builders working within legal length constraints while running a suppressor.
Misalignment between a muzzle device and suppressor can cause accuracy issues and uneven suppression. The Gemtech ETM system's engineered fit and carbon-reduction design work together to keep your setup running reliably over time.
