I posted up an add in the BX for 8 USGI AR-15 30 rounds mags I have for sale. Shortly after posting, I had a member here (with zero posts) that offered to buy the magazines. He included in the message that only high cap handgun magazines are illegal. I did a little research and I get an even amount of answers on both sides. Some say it is fine and some say it is illegal because AR magazines can be used in AR pistols, thus making it a pistol magazine capable of holding more than 30 rounds of ammunition. Anyone with info from Hawaii that has some rep here would be greatly apprciated. Let me know what you find. I am not going to sell the mags to this member until I have verified that it is legal.
