Maxim Defense DSX Series
The Maxim Defense DSX Series is the company's flagship duty suppressor, purpose-built for firearms with barrel lengths under 10.3" — including the Maxim PDX™ platform. Constructed from a 17-4 stainless steel MonoKore™ core and a Grade 5 titanium tube and mount body, the DSX features Maxim's patented M-Kore™ technology which dramatically reduces gas blowback and cyclic rate increase compared to traditional suppressor designs. SOCOM-tested and UTM-safe. Fully user-serviceable with common tools. Integrated carbon cutters in the core simplify tube cleaning. Can be pinned to a 10.3" barrel for a legal 16" overall barrel length. Available in Black, Grey, and FDE.
