The M900 Liberty Series utilizes Calico's distinctive top-mounted "Liberty" helical magazine with a rear winding hub, delivering a 50+1 capacity in 9mm Luger. The magazine cradle is marked "LIBERTY 50," and the charging handle is positioned on the side of the magazine housing for easy access.
Its operating system is semi-automatic, roller-delayed blowback. This configuration pairs with a 16-inch steel barrel and a plain, unthreaded crown. A ventilated metal barrel shroud overlays the fore-end for added protection and heat dissipation.
Sighting is handled by an integrated rear aperture/peep sight mounted to the magazine cradle, with knurled thumbwheels for windage and elevation adjustments. A front sling swivel is fitted for carry options.
The rifle features a matte black polymer receiver (lower/frame) with an integral black polymer pistol grip, paired with a matte black metal upper/magazine cradle, and black polymer furniture including a ribbed fore-end. The fixed stock features an exposed rectangular metal support bar, and the length of pull is 16.0 inches. A manual safety rounds out the control set. The "MADE IN BAKERSFIELD, CA, USA" marking appears on the metal upper/magazine cradle.
