IF you get a 100%, fully inletted stock for the rifle, it is just the same as ytaking the gun apart and reassembling it using the stock that it came with! IF you use a semi-inletted stock, you will have to remove some wood here & there in the inletting to get it together. But you'd have a better fit that way, if you can do the work or know someone who can!

The gun has a crack - where is the crack? In the wood? or what?? Picture?? Pin? You mean that little brass pin from one side to the other? That is justa reinforcement for the wood. It does noat touch any metal inside. You disassemble the 700 by removing the two "guard screws"......then take out the barreled action from the top, and the trigger guard assembly out the bottom. Then remove the magazine box from its recess.
