Not a bad article. I cant ‘disagree’ with it, but I think there are additional schools of thought that have been left out. Its hard to fully cover a topic this broad in the length of the given article. For example, for the AR platform, I am a proponent of single point slings, and the article implies a two point sling is essential. Should have just said a sling was essential, and qualified that for when its not appropriate to have a sling.
I think the significance of this article is that it was posted in The Federalist. CW is in the wind.
