Query: good for a beginner..

This video is very good for the raw beginner on the basic operations (cleaning, sight picture, sighting in, disassambly/reassembly, shooting positions, etc.) of the AR-15. At times it is a little fast going thru steps, but you can always rewind and watch that part again. After reading the marine tech manual several times, this video is a great supplement to have around to get a better basic understanding of the AR-15 operations.
