Maxim Defense Pdx Pstl 5.56 5.5" 20-Round FDE Carbine

The Maxim PDX Pistol 5.56 5.5" is a subcompact rifle platform engineered for close-quarters operations and born from real Tier 1 community requirements. At just 18.75 inches overall length with a 5.5-inch barrel, this compact powerhouse delivers 5.56 NATO velocity and terminal performance in a form factor that dominates confined-space encounters where traditional carbines are impractical. The PDX represents Maxim Defense Industries' answer to precision urban and breaching scenarios where compact handling and maximum energy delivery are non-negotiable.

The platform features a direct impingement gas system paired with the HATEBRAKE muzzle booster, which reduces recoil impulse and facilitates rapid follow-up shots—critical in dynamic entries. The ALG Combat Trigger provides consistent break weight for precision work, while the Maxim SCW PDW brace enables stable shooting from the shoulder or support position. The 5.56 NATO caliber from a 5.5-inch barrel achieves velocity sufficient for reliable performance while maintaining a profile that fits vehicle cabins, aircraft, and confined tactical spaces where longer rifles create liability. The flat dark earth finish resists corrosion in field conditions.

This platform is purpose-built for tactical professionals, special operations units, and serious training enthusiasts who prioritize compact capability for specialized scenarios. SWAT teams conducting building entries, helicopter crews, and operators working from vehicles benefit from the PDX's minimal footprint and full-power rifle output. The 20-round magazine capacity balances firepower density with control in tight spaces. Maxim Defense PDX rifles appeal to buyers evaluating alternatives to standard PDWs—those seeking genuine rifle performance without full-sized carbine proportions.
