Specifications
Description
The KGM R556A1 is a quick-detach suppressor for AR-15 rifles and carbines, built to reduce muzzle report on 5.56 NATO and 6mm ARC loads. Its nickel alloy and stainless steel construction is finished in black C Series Cerakote. The raw text states it was engineered against SOCOM specifications and survived more than 20 SOCOM SURG firing cycles.
The suppressor is 4.85 inches long, 1.75 inches in diameter, and weighs about 15.9 ounces. Its internal gas management is described as venting forward with minimal backpressure. A 1/2x28 direct thread mount is included, and the quick-detach system allows removal without tools.
Since 2024 the bore has been EDM cut to accommodate 6mm cartridges in addition to standard 5.56 NATO ammunition, so one suppressor covers both calibers.
