Rearden Manufacturing Group Llc R2S Flash Hider 1/2-28 Threads Taper Shoulder Black

The Rearden R2S Flash Hider with 1/2-28 threads is a taper-shoulder muzzle device built for shooters running Plan B compatible suppressor systems. If you're assembling a suppressed rifle around Rearden's Atlas or Atlas XL platforms, this flash hider serves as the foundation—handling the job of timing your can while presenting a clean interface for your suppressor to mount. The black nitride finish isn't just for looks; it's designed to promote a tighter seal between the muzzle device and your suppressor, which matters when you're trying to maximize sound reduction and keep your system running efficiently.

Proper setup is critical with any muzzle device and suppressor combo. The R2S requires careful attention during installation: torque the flash hider to 15–25 ft-lbs on a clean, squared shoulder, then use Rockset to lock it in place. Once mounted to your suppressor, torque the can itself to 10 ft-lbs. An alignment rod during installation ensures the entire stack is concentric and trouble-free. The nitride finish and 17-4 PH steel construction give this device the hardness to handle repeated mount-and-dismount cycles without galling or chatter.

One thing to know: shims aren't included. If you need to time this hider to a specific rotational position, or if your barrel lacks a thread relief cut by the manufacturer, you'll need to source shims separately. It's a common consideration in the Plan B ecosystem, and most gunsmiths or suppressor dealers can handle that part. When everything is torqued, sealed, and aligned, you've got a robust connection between barrel and suppressor that'll hold up to the rigors of hunting, range work, or tactical training.

Frequently Asked Questions

What suppressors work with the R2S flash hider?

This flash hider is designed as a Plan B compatible muzzle device for Rearden Atlas and Atlas XL suppressors. It provides the mounting interface between your barrel and those suppressor platforms. Always verify your specific can's compatibility before purchase.

Does this flash hider require shims?

Shims are not included. If you want to time the flash hider to a specific rotational position, or if your barrel lacks a thread relief, you'll need to source shims separately. Many barrels and suppressor dealers stock them for this exact purpose.

What torque specs should I use during installation?

Torque the flash hider itself to 15–25 ft-lbs on a clean, squared shoulder, then apply Rockset. Once your suppressor is mounted to the flash hider, torque the suppressor to 10 ft-lbs. Use an alignment rod to ensure the entire system is concentric before final assembly.

How do I maintain the nitride finish?

The black nitride finish is durable and corrosion-resistant, but keep all threads and taper surfaces clean during installation and use. Contamination can compromise the seal between muzzle device and suppressor, so inspect and clean both before mounting.
