Guys...Likely old news to many of you, but doing some research on my first AR I see that Walmart is carrying the SigM400.
A few years ago I did a paper on Walmart for school; one of the things I did discover is that they truly do require many of their vendors to create a sub-par version of their regular brands so that Walmart can offer for lower prices. Levi is a very real example, so is Toro...Levi gave in, and the 501's you buy at Walmart are not of the same quality you would get at Macy's. Toro refused, and is the reason you cannot buy Toro at Walmart.
I am surrounded by Walmarts, and their M400 prices are significantly better than I would find at Gander or Cabela's, much less the local shops. Anyone have additional info on their thoughts around Walmart rifles?
