I had never been able to find pre-bans. Im in NY so im stuck with the 10 rounders. A guy at the local gun shop tried selling my friend a bunch of pre-ban 5.56 30rd mags and told him he could use them with the 6.8, he called and was very excited until I told him no. :lol: I ordered 20 round mags that are lanced to 10rds. and was told that they could be modified to hold the 20 rounds it was intended for but they have yet to arrive so we will see!
