I'm guessing you are full of it too!
I think S&W is able to produce the Sport II for less than Ruger can produce the AR-556 due to economies of scale. Smith's use of standard parts allows them to source from more places as well, so they can probably put more rifles on the market than Ruger. This is my guess anyway.
There is a local (hour and a half or so away from me) dealer here who was advertising an AR-15 for $399.99 over the holidays. No idea what the model was, as the ad doesn't say and you had to go to the store to find out. I'm guessing either DPMS or Sport II...
