It might tempt me into buying my first Ruger. As the "race to the bottom" of sub-$300 rifles has ramped up, manufacturers need to do something to make their rifle worth buying over their competitors, besides saving the cost of a lunch.

Ruger would be the one to do it over other brands, as they are willing to test market trends and innovate where other companies won't.

I shoot Weatherby's, so I don't know about the comb issue, but I am surprised that more companies don't build their products to accept proprietary accessories. Mold a couple of aluminum 1/4"x20 inserts into the side of the factory stock and sell it with plastic plugs in them. Sell a Ruger adjustable comb for $30 that can be bolted right on with zero gunsmithing.
