Warners, I do not believe anyone is recommending purchasing a stock and assuming it is going to fit, so I will assume there is a question,
"You don't think the laminate stocks listed about would fit well enough to drop the barreled receiver in an go?"
I would suggest we think about the loose receiver, trigger guard and stock on your Mark X first, when you chambered a round by closing the bolt you were pushing the receiver forward and away from the recoil lug seating surface, this gave the receiver a running start when fired, the sudden stop crushed the fiber in the wood so every time the rifle was fired the stock got hammered,
When you install the receiver in the new stock I would suggest you pull the receiver back to seat the recoil lug then tighten the screws, there should be absolutely no space between the recoil lug and stock and the tang on the rear of the receiver should not be making contact, in time the screws will require maintenance as in at least checking.
When the receiver is loose cambering a round can push the receiver forward,firing will drive the receiver back, I am a fan of cutting down on all that travel, allowing a bullet a running start before it hits the forcing cone and rifling, in my opinion , is a good thing, excessive head space allows the head of the case to have a running start before the head of the case hits the bolt face is a bad thing, so I cut down on all that travel and if I do not cut down on bullet travel before it hits the cone/rifling? I know why.
