Maxim Defense SDX RFLX 300 Blackout Integrally Suppressed Pistol with SB Tactical SBA5 Brace

The Maxim Defense SDX RFLX in 300 Blackout (MXM49216) is an elite, ultra-compact integrally suppressed pistol platform engineered for operators and serious enthusiasts who demand maximum performance in a minimal footprint. Built around an 8.50″ barrel with an integrated suppressor, this firearm delivers dramatically reduced sound signature and muzzle blast without the added length of a conventional suppressor attachment — keeping the package tight, maneuverable, and ready for action.

Chambered in 300 Blackout, the SDX RFLX is purpose-built to take full advantage of the cartridge’s superior subsonic and supersonic performance, making it an outstanding choice for hunters, home defenders, and competitive shooters who demand versatility and downrange effectiveness from a compact platform.

The pistol ships with a 30+1 capacity and features a Picatinny rail-equipped upper receiver for easy optics and accessory mounting, an M-Slot handguard for tactical customization, and a Black Polymer SB Tactical SBA5 pistol brace for enhanced control and stability. The all-black finish gives it an aggressive, professional aesthetic that matches its performance credentials.
