I have to wonder if some of you people read the explanation of features or if you just see that your pet gun doesn't have as many Xs as you'd like and roll back to hysteria. There's all kinds of comical posts in this thread like "who needs a black insert" and "what difference does it make if there's parkerizing under the FSB or not". READ the explanation of features and decide if you need these features or not. The problem with the Chat is simply that most people can't read it objectively. Some see it and find that their pet rifle has a lot of Xs and use it to justify their purchase. Some see it and find that their pet rifle doesn't have a lot of Xs and think it means the chart is "bunk". The Chart is a collection of facts. If you don't understand, or don't care, what those facts are and/or how they relate to your needs in a firearm then ignore it. But that doesn't change the facts. And I'll say one more time, since people continue to go on about how "milspec doesn't mean anything". Milspec is the BASE standard for rifles of this type. Now go back and look at the Chart and look at how few makers even come close to meeting that standard.
