B&T XH-556 RBS Titanium Subcompact Suppressor w/ QDSF Hub

The B&T RBS XH-556 Titanium Subcompact Suppressor delivers high-performance sound and flash reduction in an ultra-compact, lightweight package designed for 5.56 NATO / .223 Remington firearms. Featuring a hybrid 3D-printed titanium body paired with a durable 718 Inconel blast baffle, this subcompact suppressor balances exceptional heat resistance with minimal added weight and length.

Key specifications include:

• Caliber: 5.56 NATO / .223 Rem
• Weight: 8.6 oz
• Length: 5 inches
• Diameter: 1.75 inches
• Construction: 3D-printed titanium body with 718 Inconel blast baffle
• Finish: Black cerakote
• Mount: 1.375×24 TPI Redshift Hub (SureFire Hub compatible)

Equipped with B&T’s Reduced Backpressure System (RBS), the suppressor limits bolt-speed increases to under 2% for reduced gas blowback, cleaner operation, and longer component life—even during full-auto fire. A low-flash endcap further minimizes visual signature for improved performance in low-light and close-quarters environments.

Weldless construction eliminates traditional weak points, while extensive SOCOM-style burn-down testing (over 22,000 rounds) confirms its durability under extreme high-round-count and high-heat conditions. Fully full-auto rated with no barrel length restrictions, the XH-556 SC is optimized for both short-barreled rifles and longer carbines.

Ideal for tactical professionals, law enforcement, and civilian shooters seeking a maneuverable, high-durability subcompact suppressor that prioritizes low backpressure, flash control, and reliable performance with a versatile 1.375×24 Redshift / SureFire-compatible hub.
