I used OD green and military mid-brown (chesnut?) over the stock finish in what i call a Tactical Tribal design, Ill post some pics when i find my camera(In the middle of moving and it got packed doh!). Ill also post some of my buddy's homebuilt barret/m4(BTAssault) as its got a pretty kickass paint scheme too.
