Keep your SIG Airgun MCX/MPX replica running with this value magazine pack — four 30‑round .177 caliber magazines (one main + three extra spares). Designed for quick reloads during target practice, training, or skirmish play, these detachable magazines fit MCX/MPX-style airgun replicas that accept .177‑cal detachable mags. Constructed from durable polymer (with metal components where applicable), each mag holds up to 30 .177 pellets/BBs and feeds reliably when used with the correct power system (CO₂ / Green Gas / spring — confirm compatibility with your specific airgun model). Great for reducing downtime and keeping shooters in the action.
