REARDEN R2S FH .375 5/8X24 GNMTL

The Rearden R2S flash hider in .375 bore with 5/8x24 threading is purpose-built for shooters running large-caliber precision rifles and big-bore hunting setups. If you're shooting .375 H&H Magnum, .375 Ruger, or similar cartridges through an Atlas or Atlas XL brake-compatible platform, this flash hider clips on seamlessly—it's also compatible with Plan B systems for those already invested in that ecosystem. The gunmetal PVD finish resists corrosion and blends into modern rifle aesthetics without the visual signature of a muzzle brake, making it a solid choice for hunters and long-range shooters who want to manage muzzle flash without adding unwanted weight or recoil direction.

Flash hiders work differently than compensators or recoil brakes. Where a brake redirects gas to manage recoil, a flash hider focuses on hiding the dust signature and flame at the muzzle—critical on low-light hunts or in field conditions where your position matters. The R2S does this while maintaining the ergonomic platform you're already familiar with if you've run other Rearden muzzle devices.

Installation is straightforward if you've threaded your barrel to 5/8x24. The compact form factor keeps your overall rifle length in check, and the gunmetal finish ages well in the field without the gloss of cheaper coatings. Pair this with quality handloads and proper barrel maintenance, and you've got a no-fuss muzzle device that works when it matters.

Frequently Asked Questions

Will this fit my .375 rifle barrel?

Yes, if your barrel is threaded 5/8x24. The .375 bore size matches large-caliber magnum rifles like the .375 H&H Magnum and .375 Ruger. If you're unsure of your barrel's thread pitch or bore, check your rifle's documentation or contact a gunsmith.

Is this compatible with my muzzle brake or suppressor system?

The R2S flash hider is designed to work with Atlas, Atlas XL, and Plan B muzzle systems. It threads on directly at 5/8x24. If you're running a different platform or planning to use a suppressor, verify compatibility before purchasing.

What's the difference between a flash hider and a muzzle brake?

A flash hider reduces the visible muzzle flash and dust signature—useful for preserving your low-light vision and concealing your position. A brake, by contrast, redirects gas to manage recoil. The R2S prioritizes flash reduction rather than recoil control.
