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

APS Remington M870 AOW sawed-off 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 APS gas gun uses a system where gas is injected into the bolt and BBs are loaded into a shell-shaped cartridge, making it a model that allows you to enjoy the realistic loading and ejection process that is the true joy of a pump-action shotgun.The main parts of the exterior are made of metal, which is highly rigid and gives it a great feel.

This sawed-off model is labeled AOW (Any Other Weapon) and is modeled after a door breaching model called a "Master Key," with the barrel shortened to the bare minimum and equipped with a folding grip at the front.

The AOW has the shortest and most aggressive form of the APS CAM MKII series, which has a gas tank inside the bolt and allows you to enjoy pump action and shotgun shell ejection just like a real gun. With a stockless pistol grip and a folding foregrip, and a magazine capacity reduced to two rounds, it's designed for instantaneous victory. Made of heavy, full metal construction, it's a product that lets you fully enjoy the appeal of a shotgun.
