Rearden Mfg R2C, 1/2-28 TPI, Square Shoulder, Black Nitride, Flash Hider

The Rearden R2C is a compact, precision-engineered flash hider designed to meet the needs of modern suppressor users and builders running 1/2x28 threaded barrels. Ideal for 5.56 NATO and other small-bore calibers, this square shoulder variant ensures optimal alignment on barrels with precision-threaded shoulders—especially important when mounting suppressors or suppressor adapters. Machined from high-strength steel and treated with a corrosion-resistant black nitride finish, the R2C offers a slim footprint with high performance. It’s designed not only to reduce visible muzzle flash but also to provide reliable compatibility with Rearden’s Atlas and Plan-B style suppressor mounts. The square shoulder geometry enhances repeatability and alignment, making it a preferred choice for precision applications and suppressor setups alike.
