Everybody beat me to the punch. I was going to suggest just what mogwai did. Also, I was reminded by Nanuk... of the lace on cheek pad. I haven't seen the Cabela's one, but there is a company that advertises regularly in the Shotgun News that sells a very nice reproduction U.S. WWII version. I think they were originally for the M1 sniper rifle, but, because they are a lace on they would fit any gun, I imagine.
Back to mogwai, for a second. A few years ago I sprained my ankle and as the doctor's nurse was wrapping it, I noticed that it was some really neat material that I had never seen before. I asked her what it was, and she told me it was called Coban (short for cohesive bandage). She went on to tell me I would need a roll of it and that the price was outrageous at a drug store but I could get it at any farm supply store as it was used to wrap horses legs.
When I went to pick some up I discovered that it could get it in colors from white to hot pink to black/white zebra stripe, to camo. I wrap a couple of my rifles with it and alternate to the season. The zebra stripe is great winter camo. It is cheap and easy to change and leaves no residue.
I'm sure most of you know what Coban or vet wrap, is but I'm just posting this for anyone that does not know about this very useful stuff.
