Les, thanks again, videos awesome - an extremely high level of competence displayed! I am not sure I aspire to that level, but instructive to see the experts do their stuff.
I am searching for a solid AR-15 civilian training course in Central or Northern California for the basics of maintenance, shooting, and field operation. If need be I have found manuals, books, videos in various on- and off-line formats, etcetera. And I do have my brother and a friend who are familar with the platform somewhat.
I, too, will require optics and all the help I can get!
