[APS] CAM870 MKII-J Marine JASG Certified Official Japanese Specification (Released October 18, 2025)

APS Remington M870 Marine Magnum live cartridge gas shotgun.

The Remington M870 is a shotgun developed by the American Remington Arms Company as a successor to the M31 shotgun. Even now, more than 50 years after its release, it is a legendary gun that continues to be widely used by military and police forces around the world, as well as for hunting by civilians.

This Marine Magnum model, as its name suggests, is used by maritime and coastal security forces around the world. Made from rust-resistant chrome stainless steel to prevent corrosion from sea breezes, this silver-colored replica is a perfect fit. Other features include an extended magazine tube for increased ammunition capacity, and a stock and fore-end made of environmentally resistant resin, making this a professional-grade model.

The Marine is a long model in the APS CAM MKII series, boasting the longest barrel length and ammunition capacity, thanks to its gas tank inside the bolt and pump action and shotgun shell ejection, just like a real gun. As its name suggests, this silver model is nickel-plated for rust and corrosion resistance, designed for use on boats and other surfaces, faithfully recreating the design of the Remington SPS Marine Magnum. Made of heavy, full-metal construction, this is a product that allows you to fully enjoy the appeal of a shotgun.
