Thanks guys...
Yeah, Walmart has at least 2 different types: MARPAT (Woodland) and MARPAT (Desert). Trouble is, it's like $7.95 a yard here... I ended up getting just a half a yard for this exact purpose. I think I'm going to go back and get some desert pattern stuff too. I actually redid the scope a bit, (after watching "Enemy at the Gates" last night), and covered my scope in frayed strips of MARPAT.
I really want to get a wood kit for the stock though. A nice dark brown Walnut stock... *drool*
