I was just looking to pick op a spare mag for my rifle. Surgeon bottom, metal and it has an AI mag in it. I can't believe the price for a spare, and the AI mags seem like they can be a little hard to find. Brownells lists an Accurate Mag as an alternative. It is in stock, and the price is a bit lower. Anyone have any experience with these? Not in any hurry and if the AI is better I will simply wait. I still can't believe the price.
