Yes. The Hammer 3-D Offset Assault is on USBC's approved ball list, approved on January 5, 2025, so it is legal for USBC certified league and tournament play. USBC updates the list weekly at https://bowl.com/approved-ball-list. If you bowl a specific event, check that event's equipment rules before you drill.
