Arms Magazine walks us through the features of the Maruzen CA870 TAC-10 airsoft shotgun in this video... "The 'TAC-10' has been added to the MARUZEN CA870 series of air-cocking shotguns, which have been highly popular among core users due to their simple pump-action firing method and high-fidelity performance with a variable hop-up system with the same structure as APS rifles. This model is based on the Remington 870 TAC-14, which belongs to a new category of 'legally owned compact shotguns' that have successfully cleared the firearms regulations recognized in the United States in recent years."
