AI makes a quality magazine don't get me wrong. We just chose to go with Accurate-Mag because they are just as good and since they are cheaper in price it lowers the price point on our products. Also Accurate-Mag offers more configurations of magazines for the AICS style long action magazines which is better for reloaders. As an example you can have a 300 Win mag magazine at 3.850" CIP and have a lot of room for VLD bullets.
