Rearden Manufacturing Group Llc R2S Flash Hider M18X1.5 Threads Taper Shoulder Black

The Rearden R2S Flash Hider is a precision muzzle device engineered for shooters who run suppressor setups and demand clean, repeatable timing. Built with a taper-shoulder design on M18×1.5 threads, it's compatible with Plan B-type suppressor mounts—the modular standard favored by shooters who want flexibility in their silencer systems. The nitride finish delivers both durability and a tighter seal, making it a serious choice for dedicated suppressor users.

This flash hider is machined from 17-4 PH stainless steel and finished in black nitride to a hardness of 67 HRC, giving it excellent corrosion resistance and longevity. Proper installation is key: the device must be torqued to the barrel (15–25 ft lbs), locked in place with threadlocker, and seated squarely against the shoulder before your suppressor is threaded on. Taking time on installation pays dividends in reliability and repeatability—critical when your optic and zero depend on consistent suppressor geometry.

The taper-shoulder interface and Plan B compatibility mean this will work with a range of quality suppressors, though careful setup is non-negotiable. Some barrels may require shims if the manufacturer didn't machine thread relief; the R2S itself does not include shims. This is a precision part for precision shooters—follow torque specs and use an alignment rod during setup, and you'll have a rock-solid muzzle device that supports both suppressed shooting and flash signature control.

Frequently Asked Questions

What suppressors does the Rearden R2S work with?

The R2S is designed for Plan B-type suppressor mounts and is compatible with Atlas and Atlas XL suppressor platforms. Always verify compatibility with your specific suppressor model before purchase.

Do I need shims for installation?

Shims are not included with the R2S. Some barrels require shims if the manufacturer did not machine thread relief into the chamber shoulder. You may need to source shims separately depending on your barrel.

How do I install the R2S flash hider correctly?

Torque the muzzle device to the barrel at 15–25 ft lbs, then apply threadlocker (Rockset) to secure it. Ensure the device sits square against the shoulder. Use an alignment rod to verify the entire suppressor system is properly aligned before tightening the suppressor to the device at 10 ft lbs. Keep all threads and taper surfaces clean during assembly.

Will this work with my Q suppressor?

The supplier notes that using the R2S with Q cans voids the warranty. Choose a Plan B-compatible suppressor to maintain full support and reliability.
