Rearden R2C Fh 5/8-24 Nitride

The Rearden R2C flash hider with 5/8-24 threads and nitride finish is a Plan B-compatible muzzle device engineered for shooters running suppressed setups or who want to tame muzzle flash on the range. Built from 17-4 PH stainless steel and hardened with a black nitride coating, this flash hider is designed to work seamlessly with Atlas and Atlas XL suppressors, giving you a modular system that indexes precisely when properly installed. The nitride finish isn't just about looks—it creates a tighter seal against your suppressor, which is critical for consistent performance and longevity.

Installation matters with this platform. Rearden ships the R2C with alignment shims to dial in perfect concentricity, and they're serious about the setup process: use an alignment rod, clean all surfaces and threads, torque the muzzle device to approximately 30 ft-lbs, and apply Rockset to ensure it stays put. When you mount your suppressor, torque it to 10 ft-lbs and verify alignment. This isn't overkill—it's how you get a system that runs reliably and safely. The 67 HRC surface hardness on the nitride finish means the R2C will handle repeated attach-detach cycles without degrading.

A critical note: using the R2C with Q suppressors will void Rearden's warranty, so if you're running a Q system, look elsewhere. But if you're building or upgrading an Atlas, Atlas XL, or Plan B-equipped rifle, the R2C gives you a durable, precision-made interface that rewards proper installation with years of dependable service.

Frequently Asked Questions

What suppressors is the Rearden R2C compatible with?

The R2C is designed to work with Atlas and Atlas XL suppressors on Plan B-compatible systems. Note that using it with Q suppressors will void Rearden's warranty.

Does this come with everything I need to install it?

The R2C includes alignment shims to ensure proper concentricity during installation. You'll need to provide your own alignment rod, Rockset, and torque wrench (or access to proper torque specifications) for a complete installation.

Why is proper torquing and alignment so important with this muzzle device?

The nitride finish creates a tighter seal with your suppressor, which improves performance and consistency. However, that seal only works if the muzzle device is perfectly square and properly secured. Using an alignment rod and torquing to spec (30 ft-lbs for the muzzle device, 10 ft-lbs for the suppressor) ensures the system functions as designed and maintains reliability over time.

What's the difference between this nitride finish and other finishes?

The black nitride coating on the R2C is hardened to 67 HRC surface hardness, making it extremely durable against corrosion and wear. This hardness contributes to a tighter, more consistent seal when your suppressor is mounted, which is critical for suppressed accuracy and function.
