I am in need of a thumbhole stock for a ruger m77 mkII with a varmint barrel. I have found one that may possibly work, if anyone has tried it and it does please let me know. The gun is a short action. If you know of a person/shop that builds custom thumbhole stocks, I ll take that info, My hand just dont fit around the grip of the factory stock well enough for comfort. Any help is GREATLY appreciated. I am almost bald from pulling my hair out. Thanks http://www.midwayusa.com/eproductpage.exe/showproduct?saleitemid=329680 This is the one that may work, but like it says, Id have to open the channel up some, I have one boyds stock that dont work, but it is a little different than this.
