Calico M-100 The carbine version of the M-110, it still has the .22 LR caliber. Calico’s fell victim to the Assault Weapons Ban and had to conform to the new laws. This one sports the wood furniture in a less aggressive look. Note the rather rare factory scope mount. Unlike the 9mm versions which eject spent cases downward, the .22 LR models eject from the side like regular rifles and handguns.
