I hope this isn't a repeat thread. (sorry if it is) I just finished my "mutt" AR and have a 20 rd colt mag with the black plastic follower and a 30 rd adventure line mag. Can I use these mags in the eyes of the law. Thanks for your help.
The only mags you [b]CAN'T[/b] use are post ban mags marked LE only or with a post ban date (unless of course you are a LEO). Everything else is ok to use.
