B&T XH-556 SC 5.56 NATO | .223 Rem 5" Titanium Grey SD-556RBS-SC-TI

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—tailored for the higher pressure demands of 5.56 / .223 firearms. By integrating B&T Reduced Backpressure System (RBS) and a redesigned low-flash endcap, this subcompact suppressor addresses common backpressure issues in short-barreled rifles and reduces flash signature that can compromise stealth in confined or dynamic environments.

Hybrid Construction for Streamlined Performance

Despite its compact footprint, the XH-556 SC combines the low weight of a 3D-printed titanium body with the focused muzzle-flash control of an Inconel blast baffle. This pairing enables it to handle punishing heat and rapid firing sequences while maintaining the agile, subcompact form needed for quick transitions and close-quarters maneuverability.

RBS Technology & Low-Flash Endcap

B&T Reduced Backpressure System (RBS) keeps bolt-speed increases under 2%, extending component life and minimizing blowback toward the shooter. On the muzzle end, the low-flash endcap reduces visual signature—especially beneficial in close-quarters or low-light scenarios.

The XH-556 SC delivers performance, durability, and weight savings in a subcompact suppressor. Whether configured on a PDW for covert missions or optimized for a minimal-footprint AR build, it offers a combination of lightweight engineering, rugged construction, and signature reduction designed for scenarios where space and speed are critical.
