The KGM R556 is a robust suppressor designed to meet and exceed SOCOM specifications for full-auto firing, accuracy, repeatability, sound suppression, and minimal impact on a rifle’s operating system.

It achieves this by efficiently managing gas flow to ensure minimal disruption to the rifle’s performance. By redirecting the gas flow away from the bullet’s flight path, it enhances precision. Simultaneously, the engineered gas flow passes through the suppressor to reduce flash, recoil, and sound.

The R556 is built to last, featuring high-quality stainless steel components and laser welded together, ensuring an extended service life, even after enduring years of hard use. 

The R556 includes one, 1/2×28 QD Muzzle Device.
