Built around Maxim Defense’s SDX platform and is chambered in .300 Blackout. It incorporates the M-Kore™ reflex suppressor, an over-the-barrel design intended to minimize overall added length while maintaining a compact, balanced configuration.
The system features a tuned gas system and an internal suppressor extension designed to work together with the reflex suppressor. When configured with subsonic .300 Blackout ammunition, the SDX RFLX is engineered for reduced sound signature and a compact overall profile.
