if you are talking about rules in the for sale section, those rules state that folks really shouldn't post unless they are asking about an item for buying.
Does not mean that you can't ask a question on that item? More like off the wall stuff that has nothing to do with buying the gun, such as "hey, this price seems high" or stuff like that (its late for me)...
