The Maxim Defense PDX 505-SPS delivers compact firepower in the proven 7.62x39mm cartridge, engineered for close-quarters applications where maneuverability matters. This short-barreled platform maximizes ballistic performance while maintaining portability that traditional rifles cannot match.
What Makes This Different
Maxim Defense built the PDX series around their proprietary Hate Brake muzzle device and integrated suppressor compatibility, reducing both flash signature and felt recoil compared to standard AR platforms. The 5.5-inch barrel achieves optimal velocity for the 7.62x39mm cartridge while keeping overall length minimal. Advanced metallurgy and precise manufacturing tolerances ensure reliable cycling with both steel-case and brass ammunition.Key Features
