The Rearden FHD Flash Hider is a precision muzzle device designed for shooters running suppressed setups with compatible mounting systems. This 13.5×1 LH taper shoulder flash hider is built to work seamlessly with Plan B-type suppressor mounts, making it a solid choice for hunters, precision rifle shooters, and tactical competitors who prioritize sound reduction without sacrificing reliability. The updated design features larger wrench flats on the rear for easier installation and adjustment in the field.
Built from 17-4 PH H900 stainless steel, the FHD is compatible with both Atlas and Atlas XL suppressor platforms, and works with Atlas XL adapters. The black nitride finish delivers both durability and a tighter seal against your suppressor, enhancing overall system performance. At 67 HRC surface hardness, this finish stands up to repeated mounting and removal without degradation—a real advantage if you're swapping cans between rifles or running multiple setups.
Proper installation is critical to get the most from this muzzle device. Use an alignment rod during setup to ensure the entire suppressor system sits square, and torque the device to the barrel per manufacturer specs with Rockset threadlocker. Keep threads and tapers clean before mounting your suppressor. If your barrel lacks a thread relief, you may need shims to achieve the correct timing—something worth checking before install. This is a working tool for serious shooters who understand that precision assembly pays off in consistency and longevity.
| Thread Pattern | 13.5×1 LH |
| Mount Type | Taper Shoulder / Plan B Compatible |
| Material | 17-4 PH H900 Stainless Steel |
| Finish | Black Nitride (67 HRC Surface Hardness) |
| Compatible Suppressors | Atlas, Atlas XL, and Plan B-type mounts |
| Shims Included | No |
The FHD works with Plan B-type suppressor mounts and Atlas/Atlas XL platforms. Check your suppressor's mount type before purchase. If you're unsure, contact the suppressor manufacturer or reach out to our team.
Shims are not included with this muzzle device. Whether you need them depends on your barrel—specifically, whether the manufacturer included a thread relief. If your barrel lacks that relief, you may need shims to time the device correctly. Shims are sold separately if required.
Torque the muzzle device to approximately 30 ft-lbs to the barrel, then apply Rockset threadlocker. When mounting your suppressor, torque to 10 ft-lbs. Always use an alignment rod during setup to ensure the system is square and concentric.
The black nitride finish (67 HRC hardness) creates a tighter seal with your suppressor, improving system performance and consistency. It also resists wear from repeated mounting and removal, which matters if you're running this device on multiple setups or swapping cans regularly.
