The Six 12 is new development in shotgun technology by Crye Precision, it is similar to the M26 LSS as it was designed as a underbarrel shotgun and could be used in a number of configurations. The Six 12 is also available in a standalone suppressed version. The Six 12 works like a double action revolver, and therefore similar to the semi auto JCS or S12K Tactical shotguns but slightly slower. The accuracy, fire rate and mobility of only -2 makes the shotgun an extremely good all around performer with excellent quick firing and movement.

The Six 12 shotgun cannot use the Ejection Port Reload this can be problematic at times. Reloads can be planned as they are much faster due to the magazine nature rather than the tube magazine found on other shotguns.
