Excellent choice. I'd urge you to mount a quality sling to it, feed it from good magazines (mil-spec aluminum with good followers, Magpul Pmag's, or Lancer L5 AWM's), incorporate a light via an FSB mount, and most importantly, get training in its proper operation via a carbine course!
Appleseed is another good option to touch up on your marksmanship basics, just buy four 20 round magazines for the Appleseed Shoot.
Aside from that, have fun, good rifle choice.
