I have a safe that is about 30 inches tall. My AR is about 32 inches long with the stock fully collapsed. Am I doing any harm to the AR if I store it in the safe by leaning it sideways on some ammo cans? The only part touching the ammo can is the hand guard. I'm not worried about scratches because I can put some padding around it. I've included a poorly drawn MS paint diagram to help people understand my question.
