Is buying a complete rifle kit the best cost effective method? - buying used rifles

I'm considering buying a car A4 Rock River Complete Rifle Kit for $ 650. The reason for this choice, because I am short on money and not interested in buying a used gun. This will be my first gun when I make a good decision? Besides, what suggestion (s) you for a first weapon in possession?
