The KGM R556A2 is a purpose-built suppressor engineered to meet SOCOM-level expectations for full-auto durability, accuracy, and repeatability. It is optimized for 5.56 NATO rifles and has an EDM-cut bore to accommodate 6mm cartridges such as the 6mm ARC. The design minimizes backpressure and redirects gas flow away from the bullet’s flight path to protect accuracy while reducing flash, perceived recoil, and sound signature across a wide range of barrel lengths, including short-barrel rifles.
