you're shopping the wrong places if those are the prices you are seeing for those rifles. Buds has the Sport, at this very moment, for $609 and free shipping. I've seen the Sport advertised below $550. http://www.budsgunshop.com/catalog/...71969/S&W+M&P15+Sport+30+1+223REM5.56NATO+16"Both are $700 +
On the topic, if I had a choice btween a $110 SKS and a $700 AR (prices I paid for my personal examples).....I might got with the SKS. With prices on both approaching $500, I'd buy the AR every time.
