In all serioousness, (Striker's post notwithstanding) you'll find a few things necessary- I suggest a hardside case. Get a buttstock cleaning kit, an Otis or other quality cleaning kit for normal use, and a spare parts kit. AR's have been known to have extractor failures, so the standard 'survival kit' is usually adequate. Get as many good 30 round mags as you can afford, USGI or Thermold. I suggest Blackhawk for any nylon gear - Mike Noell is a former SEAL team operator and knows good gear. www.blackhawkindustries.com is the address. Also suggest that you buy at least two 30 rnd mag carriers and perhaps a web belt. The manual referred to by Imbroglio is US Army FM 90-10, Military Operation in Urban Terrain. Follow the owner's manual for cleaning, and zeroing. Be patient, the AR frequently needs about 100 or 200 rounds to break in. Enjoy!
