The Rearden FHD Flash Hider in 5/8-24 is a precision muzzle device built for shooters running suppressor-ready setups. This adapter bridges your barrel to popular suppressor platforms—specifically Rearden's Atlas and Atlas XL cans, and Plan B-pattern mounts—while staying out of the way during unsuppressed fire. The 5/8-24 taper shoulder threads index directly to your barrel, and the redesigned wrench flats make installation and removal straightforward in the field or at the bench.
Built from 17-4 PH H900 stainless steel and finished in black nitride (67 HRC hardness), this flash hider handles both the abuse of repeated mounting cycles and the corrosive environment inside a suppressor tube. The nitride finish creates a tighter seal against your can's internal geometry—a feature that works only if the muzzle device itself is properly torqued, timed, and locked to the barrel. Rearden engineered this for no overrun on the Atlas XL adapter, meaning cleaner concentricity and more reliable suppressor fit across repeated installations.
This is a precision component that demands proper setup. Plan to use an alignment rod during installation to verify the entire system runs true before live fire. Your barrel threads must be clean, and the device needs to be torqued to spec and secured with Rockset or equivalent threadlocker. If your barrel came without a thread relief cut, you may need a shim to achieve proper shoulder contact—a detail worth checking before you order. Once everything is square and locked down, you'll have a rock-solid platform for fast suppressor mounting and removal without chasing zero.
| Thread Pattern | 5/8-24 taper shoulder |
| Material | 17-4 PH H900 stainless steel |
| Finish | Black nitride (67 HRC surface hardness) |
| Suppressor Compatibility | Rearden Atlas, Atlas XL, Plan B-pattern mounts |
| Installation Torque Spec | Approximately 30 ft-lbs to barrel (with threadlocker) |
| Suppressor Mounting Torque | 10 ft-lbs |
| Shims Included | No |
Yes, if you run a Rearden Atlas or Atlas XL can. The FHD is also compatible with Plan B-pattern suppressors. Check your suppressor's mount type before purchasing. Note that Rearden has stated using this device on a Q suppressor will void warranty on Rearden's side.
Not necessarily, but your barrel may require one if the manufacturer didn't machine a thread relief groove. The muzzle device must sit square against the barrel shoulder; if it doesn't, a shim brings the shoulder back into proper contact. Check your barrel before finalizing the fit.
Use an alignment rod to verify the entire system—muzzle device, barrel threads, and suppressor—run concentrically before you fire. Torque the device to approximately 30 ft-lbs to the barrel while using threadlocker (Rockset or equivalent), then verify the shoulder is fully seated. When mounting the suppressor, torque to 10 ft-lbs and confirm alignment again.
The black nitride finish carries a 67 HRC surface hardness, which resists corrosion and repeated mounting wear. The hardness also supports a tighter seal inside the suppressor. Like all precision components, it benefits from keeping threads and mating surfaces clean before each mount.
