I'm really getting the bug for an AR...I am thinking of selling my AK and whatever ammo I have for it to help fund an AR. Now I'm not looking to spend a lot, but want something decent for the money...somewhere around $700-800...now....is that feasable? Would it be a lil cheaper if I was to buy a lower and an upper seperatly? Or am I crazy to think i could get a decent one in that price range?
