Yup, the more current version is the TUSK II. The main difference is the added creamic tiles on the side skirt ERA armor and turret deigned to absorb and dissipate the HEAT round much like the ceramic tiles in body armor does. It is a more effective design since it adds another layer of protection.
M1A1 w/TUSK II
Both Tusk I and Tusk II kits are still in use beside eachother though.
Legend makes a TUSK II set as well.
