Good post Jim.
Sandy Scott the sniper Cass and I did the story on told us he modified the butt stock hand grip on his BSA T so it fit him better. When he turned it in they told him he had to pay for it, he told them to "pound sand" as he was being discharged. Sandy was one tough guy and I can just imagine the conversation that occurred.
One dare not modify anything without facing the wrath of a superior officer.
