Maxim SDX RFLX Suppressed Pistol | .300 AAC Blackout | MXM-49216

The Maxim SDX RFLX is an integrally suppressed AR-style pistol built around a proprietary over-the-barrel RFLX suppressor and an 8.5″ barrel. Chambered in .300 AAC Blackout and finished in Cerakote black, the platform is designed for compact maneuverability and reduced perceived sound when used with the integral suppression system. Pair this pistol with an Aimpoint PRO red dot (or equivalent optic under $1000) for rapid, reliable sighting without exceeding the firearm’s compact profile. Typical applications include range training and short-range hunting where legal.
