Be better off buying a 1" barrel channel stock from eBay or someplace like that & then swap the parts & then sell the stock ya have & recoup most or possibly all of your money. Lots of guys buy a fancy wood stock from Pecatonice & then swap the parts. You could put a WTB ad in the Classifieds on this site & maybe someone has an extra one, then swap parts & then sell your stock. You will need longer tang bolts if they are the kind that goes to the trigger, dif. nosecap, possibly more.
Enlarging the barrel gets into a whole can of worms, as you have to enlarge it in 5 flats & then you could have issues with RR, lock fit, tang fit, possibly trigger fit as the barrel will be in the stock deeper, etc.
One guy on her can tell you exactly what it will take, and that is Roundball. He know T/C's like the back of his hand..... :wink:
