Have an opportunity to buy a one month old, complete, 6.5 Grendel AR15 from a friend, complete rifle minus optics, for 800.00. Includes dies and brass for reloading. He even said that he would let me make payments on it. Here's the quandry. I'm too poor to pay attention most of the time. I can afford it, but I will be eating pork and beans for a month or two. Should I even be considering this until I get my taxes done or sell my dirtbike?
