Start by blending the brown sugar, smoked paprika, garlic powder, ground black pepper, and kosher salt in a large bowl to create a flavorful dry rub.
Dry the turkey tails and apply the dry rub generously, ensuring all areas are coated well.
Allow the turkey tails to marinate in the refrigerator for at least an hour, enabling the rub to permeate the meat.
During this time, preheat your smoker to a moderate heat of approximately 225-250°F.
Once the smoker is at the desired temperature and the turkey tails have marinated, position them on the smoker grate.
Allow the turkey tails to smoke for about 3-4 hours, regularly checking the temperature and adding more charcoal or wood chips as required.
Using the meat thermometer, check the internal temperature of the turkey tails. The safe internal temperature for cooked turkey is 165°F.
In the last half hour of smoking, glaze your turkey tails with your chosen BBQ sauce for a delightful, caramelized crust.
Allow the cooked turkey tails to rest for around 10 minutes before serving.
