Rearden R2S .375 Cal 1/2x28 Square Shoulder Flash Hider - Black Nitride - Plan B Compatible

The Rearden R2S is a compact, suppressor-ready flash hider engineered for 1/2x28 threaded barrels in the .375 bore class. Machined from 17-4 PH stainless steel and H900 heat-treated for maximum strength, it carries a rugged Black Nitride finish rated to 67 HRC surface hardness for outstanding wear and corrosion resistance.

The R2S features a .375 bore with a square shoulder, and is tapered to the barrel for a clean, snag-free profile. At 1.74" overall length, it adds just 1.115" to the host firearm and weighs approximately 2.05 oz. Designed as a Plan B muzzle interface, the R2S also serves as a suppressor mounting point when paired with Rearden Atlas, Atlas XL, and Plan B compatible silencers and adapters.

Shims are not included and should be selected separately to achieve correct timing. Whether building a precision rig or a duty-grade rifle, the Rearden R2S delivers the modularity and durability shooters expect from the Rearden line of muzzle devices.
