The Sig Sauer Air1 MCX is a spring‑operated 6 mm BB replica that brings the styling and ergonomics of the MCX family to a simple, reliable, cock‑and‑shoot airsoft platform. Designed for backyard plinking, basic training and entry‑level airsoft use, the Air1 MCX uses a manual cocking action (no gas, CO₂ or batteries), lightweight polymer construction, and a top rail for optics or accessories. Its spring operation makes it low‑maintenance and legal-friendly in many areas where powered replicas are restricted, while preserving the look and manual handling characteristics of a tactical carbine.
