What's the best way to spend $250 on a new AR?

Magazines, ammo, a quality sling and training..

I wouldnt mess with the trigger. Leave the stock MilSpec trigger in there.

Im a little late to the party, but I would advise getting a Surefire X300 and mount it directly in-front of the FSB in the 12 o'clock position (works great!). Put the rest of your funds toward mags.
