Magazine insert for Hi-Capa extended mag (Airsoft)

Used the outline of Blitz Saya's ultimate mag pouch as an insert to better fit my extended Tokyo Marui Hi-Capa mags in Viper extended pistol mag pouches. They work fine without, but re-inserting a mig in the pouch is cumbersome. With this insert, it's much easer, allowing faster better tactical mag changes in the field.
