I am still an the fence about a light. I might throw on on there if I can get on for cheap.
Don't put a cheap light on a top of the line rifle. You would not put wal mart plastic "spinners" on a brand new mercedes now would you? Surefire G3 nitrolen incadesent or led lights are not expensive - 60ish and the viking tactical mount is less than 25 bux.
