Palmetto State Armory showcases the Maxim Defense PDX, an ultra-compact PDW-style AR designed for a 2019 military contract, competing with the Sig Rattler. Available in 5.56, .300 Blackout, and 7.62x39, the 5.5-inch barrel makes it one of the shortest ARs on the market at 18.75 inches overall. Key features include the Maxim Hatebrake muzzle device for recoil reduction, an M-LOK handguard, full-length Picatinny rail, Radian Raptor charging handle, ALG trigger, and a CQB stock with a shortened buffer system. The .300 Blackout model features a 1:5 twist barrel, optimized for subsonic and suppressed shooting. Ideal for concealed carry, truck gun setups, or tactical applications, the PDX from Maxim Defense is a compact powerhouse built for performance.
