Rearden Manufacturing Group Llc Fhd Flash Hider 13X1 Rh Facemount Shoulder Black Nitride

The Rearden FHD Flash Hider is a precision facemount muzzle device designed for shooters running Plan B-type suppressor systems. Built from 17-4 PH H900 stainless steel and finished with black nitride coating (67 HRC surface hardness), this flash hider threads on at 13x1 right-hand and shoulders directly against your barrel to accept compatible suppressors. It's engineered for use with Atlas and Atlas XL cans, and works seamlessly with Plan B-compatible mounts—making it a solid choice for precision rifle builds where suppressor versatility and reliability matter.

This updated version features larger wrench flats on the rear for easier installation and removal. The black nitride finish not only looks sharp but also contributes to a tighter seal when your suppressor is mounted. Like all quality muzzle devices, proper installation is critical: your barrel needs to be clean, the device torqued to spec, and ideally secured with Rocksett to prevent loosening. An alignment rod during setup ensures your entire system—muzzle device, suppressor, and bore—are perfectly concentric.

One thing to know upfront: the supplier notes that pairing this flash hider with Q suppressors may void your warranty, so confirm compatibility with your specific can before purchase. If your barrel doesn't have a thread relief, you may need shims to time the flash hider correctly. Once dialed in, you'll have a rock-solid platform for suppressed shooting with minimal point-of-impact shift.

Frequently Asked Questions

What suppressors work with this Rearden flash hider?

The FHD is compatible with Atlas, Atlas XL, and Plan B-type suppressor mounts. However, the manufacturer specifically notes that using this device with Q suppressors may void your warranty, so verify compatibility with your specific can before purchase.

Do I need shims, and will this fit my barrel?

Shims are not included with this flash hider. If your barrel has a thread relief, you likely won't need them. If it doesn't, you may need shims to time the device correctly. It's worth checking your barrel specs before ordering.

What torque specs should I use during installation?

Torque the muzzle device to your barrel to approximately 30 ft-lbs, and use Rocksett to secure it. When mounting the suppressor onto the flash hider, torque the suppressor to 10 ft-lbs. Always use an alignment rod to verify the entire system is concentric before firing.

What's the advantage of the black nitride finish?

The black nitride coating provides excellent corrosion resistance and contributes to a tighter seal when your suppressor is mounted. The 67 HRC surface hardness also adds durability, though proper torquing and installation are still critical for performance.
