Rearden R2C Fh 1/2-28 Nitride

The Rearden R2C flash hider in 1/2-28 thread pitch is a rugged muzzle device purpose-built for shooters running Plan B type suppressor mounts and direct-thread cans. Its nitride-finished steel construction delivers the durability needed for hard use while maintaining the tight, controlled fit that modern suppressor systems demand. Whether you're building a precision rifle for long-range work or setting up a duty gun, the R2C gives you a reliable anchor point for your can.

Rearden engineered this flash hider with Atlas and Atlas XL compatibility, so it plays well with suppressors from multiple manufacturers—as long as they use the Plan B mounting interface. The black nitride finish isn't just for looks; that 67 HRC surface hardness resists wear from repeated mounting and dismounting, and the finish itself promotes a tighter seal between muzzle device and suppressor. That matters when you're chasing consistency in sound signature or point-of-impact stability.

Installation is straightforward but demands attention to detail. Torque the R2C to your barrel to spec, use an alignment rod to verify the system is square, and apply Rocksett to lock everything in place. Shims are included to help you dial in perfect concentricity. Once it's set, you'll have a rock-solid platform for mounting your suppressor—which you'll torque to just 10 ft lbs thanks to that nitride surface seal.

Frequently Asked Questions

What suppressors will the R2C 1/2-28 work with?

The R2C is compatible with any suppressor using a Plan B type mount interface. Atlas and Atlas XL direct-thread suppressors will also work. Always verify your suppressor's mount type before purchasing.

What thread pitch do I need?

This model is 1/2-28, the standard thread pitch for most modern rifle platforms chambered in .223/5.56, .308, and other common centerfire calibers. Confirm your barrel's muzzle threading before ordering.

How do I install the R2C properly?

Use an alignment rod during installation to ensure the muzzle device sits square against your barrel shoulder. Torque it to approximately 30 ft lbs, then apply Rocksett to prevent loosening. Shims are included to help dial in concentricity. When mounting a suppressor, torque to 10 ft lbs and ensure threads and tapers are clean.

Will this work with Q suppressors?

Using this muzzle device with Q suppressors voids the warranty on those cans. Verify compatibility with your specific suppressor before assembly.
