Rearden R2S Flash Hider Features The Rearden R2S Flash Hider is a suppressor-ready flash hider manufactured from 17-4 PH stainless steel and threaded at 5/8x24 engineered for direct compatibility with Atlas Atlas XL and Plan B suppressor mounting systems for shooters who want a muzzle device that delivers flash suppression and suppressor-ready interface in a single compact package. At just 1.6 oz and 1.74 overall the R2S is one of the most lightweight suppressor-ready flash hider options in the Rearden lineup adding minimal weight and length to the host platform while maintaining full Atlas and Plan B interface functionality. Shims are not included and may be required for proper timing depending on barrel configuration particularly on barrels where the manufacturer did not provide a thread relief. The black nitride 5/8x24 suppressor-ready flash hider is finished with a nitride surface treatment that delivers superior hardness corrosion resistance and a consistent black appearance that holds up to sustained heat cycles and repeated suppressor attachment and detachment cycles without degradation. The square shoulder design and 17-4 PH construction provide a precise repeatable indexing surface that ensures consistent suppressor alignment and engagement with compatible Atlas and Plan B adapters under hard use. Rearden was founded on the mission to be great and innovate and the R2S reflects that commitment in every machined surface and material choice.
