The Sig/Umarex MPX Air Gen 2 is a CO₂‑powered, .177‑caliber air replica of the MPX platform intended for plinking and training. It pairs a polymer/aluminum receiver and M‑LOK forend with a 30‑round rotary magazine to deliver semi‑automatic pellet fire without the need for firearms licensing in many jurisdictions (local laws vary). The Gen 2 updates typically include improved ergonomics, M‑LOK accessory compatibility, and a finish option in Flat Dark Earth (FDE).
