I posted that up back in June or so. Wasn't overly happy with the way it turned out (not to the same standard as my M24, and black sniper rifles are sexier than anything, but I bought it to play with, not to sit around at home for targets......... planning to get a Savage Arms 10FP in .308 anyways so I can have a sexy black sniper rifle again), but it'll do the job and hopefully give you some ideas.
