Tokyo Marui KSG Airsoft Gas Shotgun

Tokyo Marui KSG Gas Shotgun

Alright, let’s be honest—this thing looks like it was pulled straight out of a sci-fi flick or a modern tactical video game. The Tokyo Marui KSG Gas Shotgun is a faithful, gas-powered airsoft replica of the iconic bullpup-style Keltec KSG. But don't let the futuristic aesthetic fool you—this shotgun is built with serious CQB utility in mind. Compact, aggressive, and smartly engineered, it packs the power and flexibility any close-quarters skirmisher could ask for.

Externally, it nails the look and feel of the real steel KSG. Tokyo Marui used tough polymer for the grip, forend, and stock—just like the actual firearm—paired with die-cast metal for the barrel, rails, and internal components. The result? A shotgun that’s lightweight where it matters but still feels solid and ready for business. Rack the pump and you’ll hear a satisfying clack that just screams “let’s go.”

This airsoft shotgun features a clever dual-tube magazine system, faithfully replicating the original KSG design. You can store two spare shells in the left tube while loading the right for immediate use, with a selector switch inside the ejection port to toggle between them. Each tube fits up to seven shells—meaning a combined total of 14 can be cycled through. That’s a whole lot of firepower in a compact package.

One of the standout features is its selectable 3 or 6-shot firing mode. Just flip the lever inside the heat shield and choose between triple-shot precision or a brutal 6-BB spread—ideal for clearing tight corners or room breaching. And with the built-in double hop-up system, both modes remain surprisingly accurate, even at medium distances. This gives you way more flexibility than your average pump-action airsoft gun.

Mounting options are well thought out too. A full-length 12-inch Picatinny rail rides on top for your red dot or optic of choice, while a 6-inch rail sits under the forend—perfect for attaching a vertical grip or flashlight. Flip-up front and rear sights come included, and they’re adjustable for windage and elevation, giving you usable backup irons right out of the box.

Internally, the KSG uses Tokyo Marui’s tried-and-tested gas system, borrowed from their Breacher line. The removable die-cast gas tank sits snugly in the stock behind the rubberised butt plate and is impressively efficient, even in colder weather. And no, this isn’t a slam-fire system—each pump must complete a full cycle, which adds to the realism and reduces wear over time.

This airsoft shotgun uses standard Tokyo Marui shell-style magazines, each holding 30 BBs. They’re quick to load and give that satisfying reload feel when slammed into the breech. The metal inner frame adds structural integrity, so it’ll stand up to the rigours of CQB environments and hard gameplay without flexing or cracking under pressure.

Whether you're looking for something unique for your loadout, or a serious CQB tool with a strong tactical presence, the Tokyo Marui KSG delivers. It’s compact, powerful, and built with attention to detail that fans of realism will appreciate. You’ll be turning heads and clearing rooms with ease—no question.
