Our stocks are primarily made and inletted to fit OEM configurations so as a rule the stock will fit the action and factory bottom metal very well. The same for a factory barrel contour. Our Drop-in Stocks are offered only in factory configurations along with some popular bottom metals. Depending on your combination of action, barrel and bottom metal the fit will vary.  However when using 700 clones and aftermarket or modified parts fitting will likely be necessary. The amount of fitting required will pretty much come down to how square of a peg you’re putting in a round hole.
