|AR-15, M16 Assault Rifle Handbook
This book covers the early AR-15, M16, and M16A1 rifles. It is mostly a reprint of the military TM, but in addition includes some history and a few additional tidbits (including some nice illustrations). Recommended if you own one of the earlier AR-15's (M16, M16A1 style) as it contains all the basics.
