went shooting with a Friend of mine a week of so ago, he had just bought a new AR. after that I needed one, started cruising the internet and wound up a AR-15.Com, after a while I found someone posted info about this site, so here I am. I've ordered a complete upper, a complete lower, and 2 stripped lowers (those 2 are for the Democrats) to get me started. does any one know of a good book to buy to learn what some of the terms mean. like M4 profile, A2 and such.
