What buffer & spring on my build?

Still waiting for this upper. This barrel is a stainless 4150CMV nitrogen stress relieved, with a Type II chamber. This upper comes with a 10 rd. mag,chrome lined BCG,& mill spec charging handle for $350 & free shipping. I would like to know what 4150CMV means & if this bargain priced upper is a decent buy?
