Description

The KGM R556A1 is a compact yet 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. The R556A1 has successfully surpassed over 20 SOCOM SURG firing cycles and continued to perform. The R556A1 works on 5.56 rifles of every barrel length, and is ideal on 14.5″ and longer barrels. Beginning summer 2024, the R556A1 has the bore EDM cut open to accommodate 6mm cartridges such as the 6mm ARC.

As a minimized backpressure design, the R556A1 achieves this performance by efficiently managing gas flow through the suppressor to ensure minimal disruption to the rifle’s performance. In addition, redirecting the gas flow away from the bullet’s flight path enhances precision. Simultaneously, the engineered gas flow passes through the suppressor to reduce flash, recoil, and sound.

The R556A1 is built to last, featuring an Inconel core, with stainless steel components, and laser welded together, ensuring an extended service life, even after enduring years of hard use. Additionally, the KGM in-house finishes the R556A1 with gas-phase nitride to further harden the suppressor. The R556A1 was built to handle M855A1 from barrels as short as 6.5”. The R556A1 is finished in the durable, chemical and heat-resistant C-Series Cerakote.

The R556A1 includes one, 1/2×28 QD Flash Hider.
