The MPX PCC operates via a semi-automatic, short-stroke gas piston system with a rotating bolt. Its 16-inch steel barrel is capped with a factory three-chamber compensator for controlled muzzle movement. The build centers on a robust aluminum receiver finished in black hard-coat anodizing.
Controls are fully ambidextrous, including the safety, bolt catch, and magazine release. A flat-faced trigger provides a consistent pull. The rifle uses an AR-pattern textured polymer pistol grip for familiar handling.
The stock setup combines a factory side-folding hinge with an aftermarket Magpul MOE SL-K adjustable stock. This arrangement provides folding and telescoping adjustment, with a measured length of pull of 13.0 inches.
A long, free-float aluminum M-LOK handguard offers mounting slots at 3, 6, and 9 o'clock, complemented by a short rail segment near the muzzle. A Picatinny rail is present on the receiver, with a gap before the separate short top rail segment on the handguard. The rifle is configured without iron sights. A detachable MPX-pattern magazine supports a maximum capacity of 35+1 rounds.
