Maxim SDX RFLX .300 AAC Blackout 8.5″ Suppressed Pistol

The Maxim SDX RFLX is an integrally suppressed AR-style pistol built for compact handling and reduced sound signature while retaining the handling characteristics of a short-barrel platform. Chambered in .300 AAC Blackout with an 8.5-inch barrel, the RFLX suppressor wraps over the barrel to minimize added length and improve balance. It includes an M-LOK two-piece handguard, a full-length 1913 top rail, and an SBA5 pistol brace. A compact red-dot such as the Vortex Venom pairs well with this pistol for fast target acquisition while staying well under $1,000.

Typical applications include suppressed range training and short-range precision shooting where a compact, controllable AR-pattern pistol with integrated suppression is advantageous.
