Im going to make this short as possible. I've been living in vancouver bc for 4 years now and over that time I acquired a few guns. The guns I bought in canada i bought knowing that someday I would move back to the states, so I only bought guns that are both sold in canada and in the states, to try and ease importation/exportation. Today a nice lady from the ATF called and said there is a problem with your application. Im like oh really? Shes like one of your guns is red flagged. Oh really which one? Get this the Remington 870 is the one that was red flagged! I said are you kidding me? The shotgun of all the guns is not going to be let in? She said ya that makes no sense to her too. She said shes going to look into it. I said the gun is exactly the same as when I bought it, minus a pistol grip and surefire light. She said the note says its red flagged because it holds more than 5 shells, but I told her that mag tube is standard issue for the marine magnum model. She said that since it holds more than 5 shots its not considered a sporting shotgun. I said well I do use it for target shooting, trap and skeep, not hunting. I told her I dont hunt at all. She said we'll for now im going to red flag it and you can try and submit it again later. Weird.
