The Gun of the Week this time around is the Calico. This weapon is produced by Calico Light Weapons Inc. out of Oregon and features a unique helical magazine which mounts on top of the weapon which ejects straight down. Magazines are available in 50 and 100 round configuration, which can make for a very heavy firearms.
These weapons are produced both in select fire and semi-automatic only. They are built as both a pistol and a carbine. The pistol weighs 2 1/4 pounds with an empty 50 round magazine. It features a 7 1/2 inch barrel and fires from a closed bolt.
The company has been sold and moved several times and sales were severely impacted by the assault weapons ban of 1994, which sunsetted in 2004. They just introduced a prototype shotgun with a similar magazine design.
One of these weapons was featured prominently in a SciFi movie made in the 1990s if I remember correctly. It was used by a good-guy alien.
Weapons are currently being produced in .22 lr, 9mm and .40 caliber. They are not approved for sale in the People’s Republic of California.
