I find that this is not true. When ever I have been in a store there has been at least two maybe three new gun buyers. Usually it has been a man and a woman and they are looking for a gun for her. She is new and some of the men are new gun owners. Look at the amount of CC permits granted lately. A lot of those are new owners. Look at the shooting classes held at your local gun club. Those generaly are new onwers too. And congradulate them on taking a class. IMHO.
So how many n00bs are cool with building up stripped lowers? How many n00bs are so refined in their rifle knowledge they buy PMAGs into backorder oblivion?
