The 1440 was designed with the AR-15 and AK-47 in mind. 20″ barrel with a fixed stock, we’ve got you covered. The insert was designed to accommodate the original M16. Shotguns fit nicely in the insert as well if they have collapsible stocks. Don’t let the pictures of the rifles fool you, the 1440 can be easily configured to showcase a nice collection of handguns and other accessories as well. Also our Concealment Covers are a great asset to help conceal your firearm storage.
