XH-556 SC

A Hybrid Subcompact for 5.56 / .223 Firearms

Engineered for operators who value both maneuverability and advanced gas control, the XH-556 SC merges an ultra-compact 3D printed titanium tube with a robust 718 Inconel blast baffle—perfectly tailored for the higher pressure demands of 5.56 / .223 firearms. By integrating B&T’s Reduced Backpressure System (RBS) and a redesigned low-flash endcap, this subcompact suppressor addresses not only the typical backpressure issues of short-barreled rifles but also the pesky flash signature that can compromise one’s stealth in confined or dynamic environments.

Hybrid Construction for Streamlined Performance

Though built in a notably compact footprint, the XH-556 SC blends the low weight of a 3D printed titanium body with the focused muzzle-flash control offered by an Inconel blast baffle. This unique pairing enables it to handle punishing heat and rapid firing sequences while retaining the agile, subcompact form that operators need for quick transitions and close-quarter maneuverability.

RBS Technology & Low-Flash Endcap

By integrating B&T’s Reduced Backpressure System (RBS), the XH-556 SC keeps bolt-speed increases under 2%, extending component life and minimizing blowback toward the shooter. On the muzzle end, the low-flash endcap cuts down on visual signature—particularly beneficial for close-quarters work or low-light scenarios.

The XH-556 SC is a groundbreaking hybrid suppressor, delivering top-tier performance, durability, and weight savings in a sub-compact model. Whether you’re outfitting a PDW for covert missions or fine-tuning your personal AR build for minimal footprint, the XH-556 SC offers a powerful blend of lightweight engineering, rugged construction, and superior signature reduction—all in a subcompact suppressor tailored to excel where space and speed are at a premium.
