I am new here, as many of you probably know, and I am looking into buying a gun. I would like to get a Classic Army, because I like the metal design and I want it durable. I would like to get an M4A1 or an M15A4...I'm not sure which one, so I thought I would ask people with experience. Which one should I get, and does anyone know of the cheapest place to buy them? I'm really tight on money, because I have to save alot for college. Thank you in advance!
