Chambered in 9mm Luger, this black semiautomatic carbine includes a Timney single-stage trigger, a slim M-LOK handguard, a folding telescoping stock, and a three-chamber compensator. It provides a complete pistol-caliber rifle platform for buyers who want these components already included.

This listing is manufacturer part number RMPX-16B-9-35, UPC 798681666751. The package includes one 35-round MPX magazine.

16-inch barrel and gas-piston operation

The carbon-steel barrel measures 16 inches and uses a 1:10 twist rate. The rifle is chambered for 9mm Luger and operates semiautomatically through a gas-piston system. This combination is a defining part of the MPX PCC specification and should be considered alongside its stock, trigger, and magazine system when comparing pistol-caliber carbines.

A three-chamber compensator is included at the muzzle. SIG identifies it as a recoil-reducing feature of the factory competition configuration. The compensator, barrel, and operating system are supplied as part of the rifle; buyers do not need to source these components separately to obtain the listed PCC package.

Timney trigger and controls

The factory trigger is a Timney MPX single-stage unit with a flat trigger shape. It is one of the primary distinctions of this competition configuration. The rifle also has ambidextrous controls and an ambidextrous safety, giving it a control layout that buyers can evaluate for their preferred handling and support equipment.

Trigger shape and stock fit are personal considerations. The supplied components establish the factory specification, while actual comfort depends on the individual user and the chosen sighting system. Review the MPX owner’s manual before use, and follow the manufacturer’s guidance for inspection, maintenance, and any future component changes.

Slim handguard and adjustable stock

The slim alloy M-LOK handguard offers attachment locations for compatible accessories. Its narrower profile is part of SIG’s competition-oriented PCC design. When selecting a rail accessory, confirm its mounting requirements, screw lengths, and clearance for this particular handguard rather than relying solely on a general M-LOK label.

The five-position telescoping stock also folds, allowing the owner to adjust its fit and reduce its profile for appropriate storage or transport. Check the rifle’s dimensions in the stock position you intend to use when choosing a case. Listed overall length is 35.25 inches; SIG’s current specification presents this rounded to 35.3 inches.

The receiver has a black hard-coat-anodized finish, and the grip is polymer. SIG lists the rifle at 6.63 pounds before separately selected accessories. Added optics, mounts, and other equipment affect the complete setup’s weight, balance, and case requirements.

Magazine package and sight selection

One 35-round polymer MPX magazine is included. Listed capacity is 35+1, describing a 35-round magazine and one additional round in the chamber. Select replacement magazines specifically for the MPX platform and confirm the exact compatibility stated by the magazine manufacturer.

This listing does not include iron sights or a factory-mounted optic. Plan for a compatible sighting system and mounting hardware as part of the complete purchase. Confirm the mount and sight fit for the rifle, and follow their manufacturers’ installation instructions before use.
