Combine the brown sugar, garlic powder, salt, paprika, pepper and chili powder into a small bowl.
Mix it together to create the rub.
Pat it all over the defrosted turkey legs.
Next slather a good amount of BBQ sauce over the turkey legs.
At this point, smoke the turkey legs about 240* for 2-2 1/2 hours. We smoked ours until the internal temperature reached 165*. This can take up to 3 hours.
Half way through the smoking time, brush on more sauce.
