Rearden R2S: Where Classic Looks Meet Modern Suppressor Technology

The Rearden R2S, 1/2×28, Heat Treat, Square (.40) represents the next evolution in muzzle device design. At first glance, it appears to be a classic bird cage flash hider—a timeless aesthetic that complements any rifle build. But beneath this familiar exterior lies sophisticated engineering that solves one of the most frustrating problems suppressor users face: carbon lock.

The Taper Advantage: Say Goodbye to Carbon Lock

Traditional muzzle devices allow carbon to build up on barrel threads, eventually fusing the suppressor to the host firearm. The Rearden R2S eliminates this problem with its innovative tapered design. The taper engages before the threads, ensuring perfect concentricity while keeping carbon deposits off the threads themselves. After hundreds of rounds, your suppressor will thread on and off smoothly—no wrenches, no torches, no frustration.

Built from 17-4 PH H900 Stainless Steel

Rearden Manufacturing selected 17-4 PH H900 stainless steel for the R2S because it offers an exceptional balance of strength, heat resistance, and corrosion resistance. This precipitation-hardened stainless steel maintains its structural integrity under the extreme temperatures generated by rapid fire and suppressor use. The H900 heat treat process creates a distinctive appearance—each device has subtle finish variations that add character and individuality to your build.

Square .40 Bore: Designed for Versatility

This specific variant features a .40 caliber bore, making it suitable for a wide range of applications. While optimized for 5.56mm and .223 Remington, the larger bore diameter provides additional safety margin and can accommodate certain larger-caliber projectiles (always verify compatibility with your specific barrel and ammunition).

Suppressor Compatibility: Atlas, Atlas XL, and Plan B

The Rearden R2S, 1/2×28, Heat Treat, Square (.40) is designed to work seamlessly with the Rearden Atlas and Atlas XL mounting systems, as well as Plan B-compatible suppressor mounts from various manufacturers. This versatility makes it an excellent choice for shooters who own multiple suppressors or who may switch mounting systems in the future.
