It has been posted many times but no one seems to understand that magpul stamps all of their mags with month and year of manufacture, its the clock looking thing, and if you think you can just scrape it off and all is good you are again wrong, you will be automatically guilty, no questions asked. You had better believe that the state knows that magpul mags are marked and will be looking for them. Now if magpul were to stop marking them then all would be good, other than ak mags as they will no be produced until after the ban.
