Combine light brown sugar, garlic powder, onion powder, smoked paprika, salt, black pepper, and dry mustard in a small bowl. Mix thoroughly to create a uniform spice rub.

Place chicken legs in a large bowl. Sprinkle spice rub evenly over the chicken and toss to coat all pieces completely. Cover with plastic wrap and refrigerate for at least 2 hours to allow flavors to develop. Cooking immediately without marinating is acceptable if short on time.

In a separate bowl, whisk together barbecue sauce and water until fully combined. Set aside for basting during grilling.

Clean and oil grill grates thoroughly. Preheat grill to medium heat, approximately 350°F (177°C).

Place chicken legs on the grill. Close lid and cook, turning every few minutes, until the internal temperature reaches between 130°F and 140°F (54°C to 60°C), about 15 to 20 minutes. Monitor grill temperature and adjust to avoid overheating.
06 -
Baste chicken legs on both sides with prepared barbecue sauce. Continue grilling, turning every minute and reapplying sauce, until the internal temperature reaches at least 165°F (74°C), approximately 10 additional minutes. For extra tenderness and darker, crispier skin, cook up to 180°F–190°F (82°C–88°C).

Remove chicken legs from grill once desired doneness is reached. Allow to rest briefly before serving to retain juices and enhance flavor.
