What are you trying to do? What is your level of experience? Do you own a rifle? Are you speaking of Carbine-based training or a marksman type rifle?
The Arms Room on 45 in League City has some great instructional courses including basic terms, safety, cleaning and live fire. If that's anywhere near you I would check them out.
its been a while since ive been to bass pro shop but i believe they offered basic rifle training and maintenance.
