The Rearden R2 is a closed-prong flash hider engineered for shooters running suppressed 5.56mm and .223 Remington rifles. Built from 17-4 PH stainless steel and finished in black nitride with 67 HRC surface hardness, this muzzle device pulls double duty as both a flash hider and a suppressor mount. Compatibility with Atlas, Atlas XL, and Plan B mount interfaces makes the R2 a practical choice for shooters who want mounting flexibility without swapping muzzle devices between range sessions and field use.
Rearden designed the R2 with a tapered section before the threads to improve concentricity when mounting suppressors. This taper also prevents carbon buildup on the threads after hundreds of rounds, a common problem with conventional flash hiders that can make suppressor removal difficult. The closed-prong geometry reduces muzzle flash signature while maintaining a compact profile. With a 0.375-inch bore size matched to 5.56mm projectiles, the R2 provides proper gas seal and alignment for consistent suppressor performance. Installation requires approximately 30 ft-lbs of torque. Shims are not included but may be necessary depending on your barrel's shoulder timing.

The R2 fits shooters building suppressor-ready AR-15 platform rifles who value the ability to swap between different suppressor brands using a single muzzle device. The 1/2-28 thread pitch covers standard AR-15 and most 5.56mm barrels. Whether you run an Atlas-pattern can from Rearden or a Plan B compatible suppressor, the R2 provides a solid foundation. We stock additional muzzle brakes and compensators for shooters prioritizing recoil management over flash reduction.
The Rearden R2 is compatible with suppressors using Atlas, Atlas XL, and Plan B mount interfaces. This includes cans from Rearden, Q, and other manufacturers who have adopted these industry-standard mounting patterns for quick-detach suppressor attachment.
No, shims are not included with the R2. If you need to time the flash hider to a specific orientation on your barrel, you will need to purchase shims separately. Installation torque should be approximately 30 ft-lbs for proper mounting.
The 1/2-28 threaded Rearden R2 has a 0.375-inch bore size, designed specifically for 5.56mm and .223 Remington calibers. This bore diameter provides proper projectile clearance while maintaining optimal gas seal for suppressed shooting.
The taper before the threads serves two purposes. First, it improves concentricity when mounting a suppressor, ensuring proper alignment. Second, it prevents carbon buildup on the threads after extended firing, making suppressor removal easier even after hundreds of rounds.
