Went to a gun show this past weekend and for whatever reason saw a huge amount of pre-ban uppers for the AR-15. My AR is post ban and I did not buy one, but my question is how can the average person tell if a lower is pre-ban or not? Are we suposed to check it by serial number? Also, if a dealer sells a post-ban lower and tells you it is pre-ban, is the consumer still responsible?
I suppose I already know the answer to the last one.
