The Dillon DRC556 Hush is a direct-thread/quick-attach suppressor system engineered to reduce the audible report of 5.56 NATO/.223 Remington rifles while preserving reliability and accuracy. It uses a modular baffle stack and high-temperature materials to absorb and cool propellant gas, helping to mitigate muzzle blast and recoil impulse relative to an unsuppressed rifle.

The Hush series includes a dedicated mounting kit tailored to the host thread pattern (typically 1/2×28 for 5.56), allowing secure interface and repeatable return to zero when properly installed. Construction features corrosion-resistant materials and internal baffling optimized for sustained use, and the overall length and diameter balance sound reduction with maneuverability on compact and full-length rifles alike.
