Im in the process of building a bolt gun off of a Remington clone and wonder what everyones thought is of integral recoil lugs and rail vs pinned or screwed in rail. I get the point of an action that has an integral rail to ensure everything is squared...but id hope with how tight of tolerances the reputable companies follow, everything should be pretty straight. It seems like a lot of the actions have a pinned recoil lug so is it worth the extra money to move up to a model/brand that is integral? What is the disadvantage of a pinned recoil lug?
