The Rearden R2S Flash Hider with 5/8-24 threads is a taper-shoulder muzzle device designed for shooters who run Plan B-type suppressor mounts. If you're building a suppressed rifle and need a precision flash hider that integrates cleanly with modern quick-detach silencer systems, this is a solid choice. It's engineered for 17-4 PH stainless steel construction and works with both Atlas and Atlas XL platforms — though compatibility hinges on proper installation and alignment, which we'll cover below.
The black nitride finish (67 HRC surface hardness) provides a durable, corrosion-resistant coating that also helps create a tighter seal when mated to a suppressor. That hardness comes with a trade-off: the finish demands meticulous setup. A loose or misaligned device won't perform as intended, and the suppressor won't seat correctly. This isn't a "crush fit and go" accessory; it's built for shooters who understand the importance of proper torquing, alignment, and maintenance.
Installation requires an alignment rod to verify the entire system sits square and true. Torque the muzzle device to the barrel at 15–25 ft-lbs and use Rockset (or equivalent threadlocker) to lock it in place. Once that's solid, clean the threads and tapers, then mount your suppressor and torque it to 10 ft-lbs. The shims aren't included with this hider; you may need them if your barrel lacks a thread relief groove, so check your barrel before ordering. Pro tip: if you're pairing this with a Q suppressor, be aware that doing so will void Q's warranty — this is a Plan B ecosystem device.
| Thread Size | 5/8-24 |
| Mount Type | Taper Shoulder (Plan B Compatible) |
| Material | 17-4 PH Stainless Steel |
| Finish | Black Nitride (67 HRC) |
| Recommended Muzzle Device Torque | 15–25 ft-lbs |
| Recommended Suppressor Torque | 10 ft-lbs |
| Shims Included | No |
The R2S is designed for Plan B-type quick-detach mounts and is compatible with 17-4 PH Atlas and Atlas XL platforms. It is not compatible with Q suppressors, and using it with Q cans will void Q's warranty. Always verify your suppressor's mount type before purchasing.
Shims are not included with the R2S. You may need shims if your barrel does not have a thread relief groove. Check your barrel specifications before installation to determine if shims are required for proper timing.
Use an alignment rod to ensure the system is set up square. Clean all surfaces, then torque the muzzle device to the barrel at 15–25 ft-lbs and apply Rockset (threadlocker) to lock it in place. Once the barrel is set, clean the threads and tapers, mount your suppressor, and torque it to 10 ft-lbs. Verify alignment before shooting.
The black nitride finish provides both durability and a tighter seal between the hider and your suppressor. The 67 HRC surface hardness ensures the muzzle device can handle the stresses of repeated mounting and use. Proper torquing and Rockset application are critical to realizing these benefits.
