It's the BX25 mag made together with 2 mags. Holds 50 rounds, in the same way you'd put 2 AR mags together with the mag clip. Shoot 25, flip over and shoot another 25.
I just saw it and had never seen it. It seems it's price is a lot like P938 mags, and is simply high because of low availability. They are selling on gunbroker for up to $165.
