The Maxim Defense SDX:508 is an integrally suppressed AR-platform firearm pairing an 8.5-inch barrel with the integrated DSX-D suppressor and MonoKore technology, billed by Maxim as one of the most robust suppressor systems in its category. SOCOM-tested across calibers, it reduces report and recoil while increasing accuracy, riding on a Gen 7 CQB stock with HK-height rail and M-slot handguard. Chambered in 5.56 NATO, .300 BLK or 7.62x39 and built from titanium and stainless steel.
