I seriously doubt anyone ever "freaks out" about a bos, I suspect most if not all just move on to look at other firearms. I would counter that the guys who DEMAND a bos are the ones that are easily freaked out otherwise they wouldn't need one to make themselves feel better when in reality a bos does nothing to benefit or protect them.Just my opinion but in my trades here if I’ve asked for a Bos and get attitude there’s a reason. Guys who refuse to do one may have a fundamental problem with it or may just not be able to purchase a gun. There is a certain level here especially now of people who are buying who can’t legally own. If I ask for a dl, carry, and bos and my price is less than retail most guys wouldn’t have an issue and several times I’ve said don’t worry about it. The guys who freak out at the mention of it I’d rather not do business with anyway
If want to know to know if a guys hiding something ask to see his weapons permit. If they don't have a weapons permit or aren't an active member of the military or LE then I'd question it
