If it doesn't already have one, get a one size bigger charging handle latch, from Brownells or Midway, Bravo Co. etc,...
http://www.brownells.com/.aspx/pid=41005/Product/AR-15-M16-OVERSIZED-CHARGING-HANDLE-LATCHThey have standard (stock), medium (which I own), and large (too big IMHO), but maybe not for you.
If it has a standard flash hider, consider a compensator (I use a Miculek) $30 from Cheaper Than Dirt.com...
http://www.cheaperthandirt.com/ARR535-1.htmlKeeps the rifle flat and makes follow up, rapid fire shots tight, as the moderate recoil from a .223/5.56 is reduced even more, although the gun gets a wee bit louder....
Spare parts kit from any reputable manufacturer, DPMS, BUSHMASTER, make great kits to have on hand.
As posted, mags & ammo, more mags and ammo. Target shoot with .223, stockpile 5.56 when you can.
I also love my AK, as it only takes a steel toed boot and a hammer to fix,.....the AR,,,,well it's a bit more "refined" so spare parts are a must, especially if BHO get re-elected...
Don't go crazy with accessories...Keep It Simple..
Oh and finally, ENJOY IT!!!! Congratulations!!!!!
I built my own AR after I "Caved".....
