Well I suppose thats as good a reason as any.. The stock horn, mounting point, might be replaced with an alloy unit.. all these weight reduction components would custom fabricated as no one makes any such thing that I'm aware of.. Even an alloy receiver could be fabricated..with proper ATF paper work.. with the right barrel and an agressive weight reduction policy 20% perhaps even more could be removed. It would almost certainly be horribly expensive but the rifle would surely be unique!!
