I think it's interesting to learn about some other aspects of the stock that might not be obvious. For example, the pillars have line contact with the receiver and are the same length front and rear which necessitated designing new action screws. You might wonder why the stocks are made this way and the truth is that the molding vendor requested this because they didn't want their operators to have to place different pillars in the correct locations in the mold. They asked for an idiot proof design and so one pillar was designed that requires no specific indexing, orientation or location. This is an example of where a decision was made simply to help the vendor.
