There are probably many fine gunsmiths building silhouette gear with whom I'm unfamiliar but two of the best in the silhouette game are Mark Pharr in Round Rock, Texas and Marvin Pearson in Chehalis, Washington.
I 'think' that Mark follows this board.
Marvin is Metalhead on here.
They both shoot silhouette and they're both knowledgeable.
Mark has a new, proprietary hunter stock design that looks very good.
Marvin's much closer to you.
