Rearden
The Rearden R2 Flash Hider is a precision muzzle device built for shooters running suppressor-ready AR platforms. Designed with a 13.5×1 LH (left-hand) threaded interface and taper shoulder design, this flash hider integrates directly with Plan B type suppressor mounts, making it an excellent choice if you're building a suppressed rifle system where timing and repeatability matter. The black nitride finish delivers both durability and a tighter seal than standard finishes—critical when you're stacking precision components.
This is a muzzle device first, flash suppression second. If your build philosophy centers on quiet, the R2 works with your suppressor's indexing system rather than against it. Rearden designed it to mate cleanly with 17-4 PH Atlas and Atlas XL compatible systems, and the taper shoulder ensures a solid, repeatable connection. The nitride hardness (67 HRC) means it'll handle the heat cycles of frequent shooting without degrading the seal surface over time. That said, this is a precision fit—proper installation matters as much as the component itself.
Setup is straightforward if you follow the fundamentals: torque the muzzle device to the barrel at roughly 30 ft-lbs with Rockset applied, verify the shoulder sits square, and use an alignment rod to confirm the whole assembly runs true before mounting your suppressor. A few critical notes: shims are not included, and your barrel may need one depending on how the manufacturer handled the thread relief. If you're running a Q suppressor, check your warranty—Rearden notes that pairing this device with certain cans may void coverage. Clean threads and tapers before assembly, then torque the suppressor to 10 ft-lbs and verify alignment one more time.
Built for ARs configured for suppressed shooting, this R2 is the kind of component that rewards attention to detail. It's not a set-it-and-forget-it part—it's a precision muzzle interface that expects you to do the work right the first time.
| Thread Size | 13.5×1 LH (Left-Hand) |
| Mount Type | Plan B Compatible / Taper Shoulder |
| Material | 17-4 PH |
| Finish | Black Nitride (67 HRC) |
| Recommended Barrel Torque | ~30 ft-lbs (with Rockset) |
| Recommended Suppressor Torque | 10 ft-lbs |
The R2 is designed for Plan B type suppressor mounts. It is compatible with 17-4 PH Atlas and Atlas XL systems. Rearden notes that use with Q suppressors may void your warranty, so verify compatibility with your specific suppressor before purchase.
Shims are not included with this muzzle device. Depending on your barrel's thread relief design, you may need shims to achieve proper timing. If your barrel manufacturer did not include a thread relief, a shim kit will likely be required.
Torque the muzzle device to your barrel at approximately 30 ft-lbs using Rockset. Ensure the taper shoulder sits square against the barrel shoulder. Use an alignment rod to verify that the entire system runs true before mounting your suppressor. When installing the suppressor, torque it to 10 ft-lbs and confirm alignment again.
The black nitride finish creates a tighter seal compared to standard finishes, which is important for suppressor performance and longevity. However, proper torquing and installation of both the muzzle device and suppressor are equally critical to maintaining that seal over time.
