Calico M900 9mm Carbine
The Calico M900 is a unique 9mm carbine from the 1980s, notable for its top-mounted 50 or 100-round cylindrical magazines. Its design, influenced by the H&K MP5 with a roller-locked blowback system, faced challenges due to the 1994 Assault Weapons Ban. While a fun collector's item, its reliability is considered average, with the 50-round magazines performing better.
