I was told by a gentleman at Alamo precision that they make a thousand or more rifles a year that is a semi production rifle they can't begin to build with the attention to the very fine details of a true custom rifle like making sure the receiver threads are single point cut to be concentric with the bolt raceway ,the receiver lugs are trued ,and the receiver face is trued, the recoil lug is pinned, the bolt lugs are trued, the bolt face is trued, install M16 extractor if the customer requests it and side bolt release and bush the firing pin hole and turn down the firing pin, type of crown, muzzle brake
now the stock you start with a good fit and then stress free bedding where you can eliminate stress on the action now you need to fit the stock to the customer IE. length of pull finger grooves ajustable comb type of finish recoil pad
Buy a Defiance action and you don't have to do all that action hocus pocus...
