The Siege ROC-556K is a 5.56mm Linear Diffuser Array silencer built around Siege's STRONGHOLD Bravo/HUB mounting system and HAVOC flash hider, and is Plan B compatible. It's designed to reduce sound and flash signature while keeping back pressure low, and performs well on 6mm ARC platforms.

Its internal design is maintenance-free, manufactured using a proprietary bonding process rather than 3D printing, giving it smooth, polished internal surfaces that resist carbon buildup.
