Okay guys, I'm new here and generally new to the world of field craft. That being said I have my mind wrapped around a lot of the techniques, but I'm curious about hiding my scope. I saw on top sniper that they made a "birds nest" by stuffing grass in the sun shade of a marksmans scope, but how practical is that? Are there other options other than a lens cover? Pics would be great because I'm more of a learn by seeing and doing as opposed to reading. Thanks in advance guys.
