Building off the success as its predecessor and based of Sig Sauer’s renowned pistol-caliber SBR, the MPX Gen II CO2-Powered Pellet Rifle is ideal for tactical drills, target practice, or just plain recreational plinking. It features all of the same features as the Gen I, but comes equipped with several upgrades to enhance performance and reliability. These improvements include a metal housing receiver for a little more weight and greatly enhanced durability, and a flat-blade trigger provides a smooth, comfortable pull. Another notable upgrade is the inclusion of a full length picatinny rail and M-LOK attachment points on the handguard – these features allows the user to use the same accessories on both the pellet rifle and centerfire rifle. The controls of the MPX Gen II CO2-Powered Pellet Rifle are also modeled after the 9mm version with the ambidextrous safety selector switch and magazine release button being located in the same positions as the pistol-caliber version. The magazine is also detachable, and uses Sig Sauer’s innovative 30-round rapid-fire belt-fed design. In addition, the MPX CO2-Powered Pellet Rifle is compatible with both 90gr and 88gr CO2 cylinders, which are installed in the hollow section of the buttstock.
