Powered by an 88/90 g CO2 cylinder located in the stock, the MPX delivers semi-automatic handling in .177 caliber (4.5 mm). The rifled steel barrel and RPM (Rapid Pellet Magazine) belt-driven feed system provide fast follow-up shots with a 30-round capacity.
External controls follow the AR pattern for familiar handling, complemented by a right-side ejection-port cut. The fixed black synthetic stock and black synthetic pistol grip offer a durable, consistent interface.
A full-length Picatinny top rail runs the receiver for mounting compatible accessories, and the handguard adds short bolt-on rail sections. Polymer flip-up front and rear sights come installed for ready use.
The factory packaging notes "Up to 600 FPS," aligning with the MPX’s CO2-powered, belt-fed design. A measured 7.0 lb trigger weight supports predictable, repeatable shots.
This example is factory new and ships complete with owner’s manual, pellet seating tool, and installed SIG AIR RPM magazine.
