As long as you have your LTC and no shoulder thing that goes up, your SHTF cleared! Otherwise will have to lay down your arms and watch out for fans...
I've got 5 Butler Creek 25 rounders new in package, complete with the receipt from Four Seasons dated pre Sept 94. Not for sale, targeted for my kids if they are not smart enough to move out of this state.
I've got some metal lipped ones that I use for myself as well.
