what have you decided to do,,,as was said earlier you have a 900$ stock and 600$ bbl (blank+gunsmithing) and a 300 $ Remington action,,,,the factory will do you no good,,,just weld the hole in the back and re-drill it,,,or remove the action and try another Rem action and see if the fit and headspace are acceptable,,,good luck if the acton and or bolt are "trued",,,,what a mess,,,you can see why most folks are using custom actions which operate much smoother ,before they pour $$$ down the rat hole,,,,Roger
