I don’t have an A-5, but have a Remington Model 11, made in 1942. It is a clone of the A-5, without the mag disconnect. I inherited mine and when I got it, it was in bad shape. I thought enough of it to have it restored. I set mine up for IPSC 3-gun competition. It has a 25” barrel, with removable choke tubes, an MMC rear ghost ring sight, and an AO front blade on a Williams base. I also have a Choate extended mag for competition. It shoots inexpensive Foster slugs into less then 3” at 50 yds. Works great. I also use it for Sporting Clays. Works well there, too.
