B&T XH-556 SC Titanium/Inconel 5.56mm Suppressor Rotex/SF Mount - HUB Compatible

The XH‑556 SC delivers a powerful blend of maneuverability, durability, and advanced gas control. Its hybrid construction pairs an ultra‑compact 3D‑printed titanium body with a heat‑crushing 718 Inconel blast baffle—an ideal combination for the intense pressure and thermal load of 5.56 / .223 platforms.

With B&T’s Reduced Backpressure System (RBS) and a redesigned low‑flash endcap, this subcompact suppressor dramatically reduces blowback, stabilizes bolt speed, and cuts down on visible flash—giving operators a cleaner, more controlled shooting experience in confined spaces or low‑light environments. Despite its compact 5‑inch length and featherweight 8.6‑ounce profile, the XH‑556 SC is engineered for extreme use, including full‑auto fire and short‑barreled setups, without imposing any barrel length restrictions.

Hybrid Titanium / Inconel Build
Lightweight 3D‑printed titanium tube paired with a 718 Inconel blast baffle for exceptional heat and pressure resilience.

Reduced Backpressure System (RBS)
Limits gas blowback and keeps bolt‑speed increases under 2% for smoother, more reliable operation.

Low‑Flash Endcap
Minimizes muzzle flash to preserve situational awareness in tight quarters or low‑light environments.

No Barrel Length Restrictions
Rated for full‑auto fire and optimized for 14.5″+ carbines while performing reliably on shorter barrels.

Weldless 3D‑Printed Design
Eliminates traditional weak points, enhancing structural integrity under extreme firing cycles.

HUB Interface Compatible
Works with 1.375×24 TPI HUB mounts and includes ROTEX / SF HUB options for flexible attachment.

SOCOM‑Level Durability
Survived 22,000+ rounds during burn‑down testing (240‑round cycles × 95 repetitions).
