Stocks with 3" Forearms

[Nodak7mm]

In the interest of my further quest for knowledge... :

I am curious as to why to stocks with wide width forearms such as the std 3", tend to run the full 3" width (almost) the full length (10"-14") of the forearm when you really only utilizing say 4"-6" on the rest top? An example would be the Tooley MBR or the MasterClass F-Class Prone....

Cause thats the way they have always made them?

Need the weight/mass/support?

Any specific reason I am overlooking?

Just wondering..

Thanks

Rod

Rigidity most likely.I have one and it is sturdy and cant bend it like the factory ones do.
