LEGO Combat Crawler X2 (7721) was released in 2007 as part of the Exo-Force theme, with 581 pieces and 3 minifigures. That makes it the 5th largest of the 41 Exo-Force sets in the catalog.

Released in 2007, 19 years ago, well past the two-to-three-year run most LEGO sets get, so it is almost certainly out of production.
