I bought my M400 in April 2015. Before I bought it I did a lot a research on it. And every pic of it I saw showed a gray metal magazine, and the safety switch was on one side. The pics I saw were from 2012ish. When I bought mine again in '15 I was very pleased to see my M400 had a nicer looking black magazine and the put the safety lever on both sides, instead of just a notch to see if if it was on safe or not. I was super stoked to see I had a decent scope too! But I don't know if the M400 SRP always had a scope. THIS POST IS JUST FYI
