John,yes your classic auto's would draw attention,just as a GI 45 or M1 carbine or 98k because they are all classics.You prove my point.
Why would I clean a rifle at the range? Stupid question.I guess you were not trained proberly.How many have gone home and do not clean their rifle till the next day or forget until the next shooting match.I've seen it many times.
And as far as the old M16icon being different than the new breed. What's the difference? A new barrel, different sights and different handguard.
Everything else is still interchangeable
