The PX-9 runs a simple blowback action tuned by PSA's Gen4 Hybrid 9mm BCG with a 5.56-style external extractor. This setup delivers dependable cycling with 9mm Luger while maintaining familiar AR controls. A slick-side upper keeps the profile clean and streamlined.
The 16 inch chrome-moly vanadium steel barrel is nitrided for durability and corrosion resistance, cut with a 1:10 twist, and threaded 1/2x28. An A2-style 9mm flash hider is installed at the muzzle. The free-float 15 inch aluminum M-LOK handguard provides mounting slots at 3, 6, and 9 o'clock for accessories, and the receiver carries a continuous Picatinny rail for mounting optics.
Controls are straightforward, with a manual safety, a standard magazine release, and a left-side bolt catch/release. The charging handle features an extended red-anodized latch for confident manipulation. A single-stage curved trigger offers a familiar AR-style press.
Furniture includes an adjustable polymer stock and a Magpul MOE pistol grip for secure handling. The 7075-T6 aluminum receivers wear a hard-coat anodized finish and are made in the USA. The rifle is Glock-pattern magazine compatible and ships with a 10-round magazine, delivering a 10+1 capacity.
An installed micro reflex red-dot sight provides an immediate, ready-to-use aiming solution. With its AR-9 layout, durable materials, and clean execution, this PX-9 is a streamlined 9mm carbine configured for practical range work.
