I see ton's of posts of "I want a 6920 with xxx roll mark", many looking for the LE only ones.

I understand some of the "sporter" or "SP" ones are semi rare?

I see when someone posts they got a rifle one of the very first questions are "what roll marks does it have".

I's this simply a collectors thing?

Does it really matter if you just want a quality dependable rifle?

Do people think they are cool because they have something marked LE only?

Inquiring minds want to know. What is the deal with roll marks?
