I've got one of the Sporticals, and the thing is more accurate that I am. Good basic AR-15. I'm half tempted to pick up another at this price...but I'd really prefer to actually "build" my next AR, just for the sake of gaining a little more firepower between the ears.
But if you're in the market for a bargain AR, these deals are really tough to beat. DPMS offers an outstanding cost to performance ratio in my opinion.
