SIG Sauer MPX 8" SBR Semi-Automatic Carbine / 9×19 mm

The SIG Sauer MPX 8" SBR is a compact semi-automatic carbine chambered in 9×19 mm, designed for shooters who value intuitive controls, modern ergonomics, and accessory compatibility. Built on the proven MPX platform, it offers stable operation, balanced handling, and full readiness for optics and modular accessories.

Compact configuration with practical handling

The 8-inch barrel provides a compact overall length, making the MPX well suited for dynamic shooting and use in confined spaces. The balanced layout remains stable even when equipped with optics or a weapon light. A factory-installed flash suppressor helps manage muzzle flash during rapid fire while maintaining controllability.

M-LOK fore-end and mounting options

The free-floating fore-end features an M-LOK interface, allowing clean and flexible installation of accessories such as grips, lights, or laser modules. A full-length Picatinny top rail provides a stable mounting platform for iron sights and optics, supporting low-profile and streamlined configurations.

Sighting systems and optics readiness

The carbine is equipped with folding backup iron sights that remain usable when optics are mounted. The platform is designed for direct mounting of red dot sights without additional modification, allowing a smooth transition between iron sights and optics depending on shooting conditions and preferences.

Ambidextrous controls

Fully ambidextrous controls allow comfortable operation for both right- and left-handed shooters. The safety selector, bolt catch, and magazine release are easily accessible and designed for confident use, even during rapid or dynamic handling.

MPX platform compatibility

Built on the MPX platform, the carbine maintains compatibility with MPX magazines and accessories. The system is known for its reliable function, soft recoil impulse, and consistent shooting characteristics, making it suitable for training, sport shooting, and professional applications.
