    I haven't seen any mention of the rifle that I own. I have a 556 xi multi caliber with a 556 upper attached presently. I am looking for two things. The first is a lower forend with a rail. The second is a 7.62x39 complete upper. Most of my mags are already stanag and would like to have the option to switch at will. Can anyone help?
