Short-barreled 5.56/.223 platforms demand suppressors that balance minimal footprint with high-temperature durability and advanced gas control. Operators outfitting PDWs or compact AR variants need a solution that reduces backpressure, limits flash, and stays light enough for dynamic handling without sacrificing durability under rapid strings of fire.
B&T XH-556 SC is a hybrid subcompact for 5.56 / .223 firearms that combines a 3D printed titanium tube with a 718 Inconel blast baffle to handle the pressure and heat of these calibers while keeping weight low. Shop this product

Design and Construction
The XH-556 SC’s hybrid construction is purpose-built: a 3D printed titanium outer tube provides significant weight savings and an ultra-compact footprint, while a 718 Inconel blast baffle is positioned to absorb and manage the punishing heat and erosive effects of 5.56/.223 blast. This pairing allows the suppressor to survive hard use and rapid-fire sequences where all-titanium designs might falter.
Performance and Gas Management
Reduced Backpressure System (RBS)
B&T integrated its Reduced Backpressure System (RBS) to address the classic short-barrel problem of increased bolt speed and rider wear. Specified to keep bolt-speed increases under 2%, the RBS extends component life and limits shooter-facing blowback—critical on duty or training ranges where reliability and comfort are priorities.
Low-Flash Endcap
The redesigned low-flash endcap minimizes visible muzzle signature, helping preserve stealth in confined or low-light environments. For operators working in CQB or other dynamic settings, reduced flash lowers the chance of compromising position during transitions.
Applications and Fitment
Optimized for 5.56 / .223 rifles and PDWs, the XH-556 SC is ideal for anyone seeking a true subcompact suppressor that won’t overburden a lightweight platform. Its robust blast baffle makes it suitable for rapid-fire training, while its compact length aids maneuverability in close quarters.
