I think that during 2017 you will see the Sport II selling for $499 + shipping or less often!
They are producing tons of them and everyone in the chain needs to move the metal. In a crowded market they are going to have to drive the Sport II on price. There are tons of sub $500 rifles like Anderson which are similar in configuration.
If things fall the right way for me this year and the price dips below $500 I am going to pick up a few as truck/car carbines! Slap a used or on sale Aimpoint Pro and you have a perfect $800 car carbine. LOL
Use should dictate gear!
