APS CAM MKIII-MR - CAM870 Marine Co2 Shell Ejecting Airsoft Shotgun in Silver

The APS CAM870 Marine MKIII-MR isn’t playing around. This is the kind of airsoft shotgun that makes your mates turn their heads the moment you rack it. Full-metal, silver-finished, and shell-ejecting with authority — it doesn’t just perform, it performs with attitude. If you're after a premium gas-powered airsoft shotgun that’s as close to the real deal as you can get without a firearms licence, this one’s for you.

Let’s get the headline stuff out of the way: this beast fires 12 BBs per shell in full Shower Mode. That’s a tidal wave of plastic hate per trigger pull. And yeah, it ejects those shells like a Hollywood action flick with every pump. It’s messy, aggressive, and downright fun — especially in tight CQB situations where you're clearing rooms and catching opponents off guard. If you’ve never experienced shell ejection in-game, be warned: it’s addictive.

The Marine edition brings a distinct aesthetic and purpose-driven build. That silver marine finish isn’t just for show — it's built to resist the elements, much like a real-world maritime shotgun. Paired with black synthetic Magpul-style furniture, the combo screams tactical and durable. It’s the sort of finish that can handle rain, sweat, mud, and still look sharp doing it. The stippled grip areas on both the buttstock and forend give solid purchase, gloved or not.

Internally, the MKIII upgrades over its predecessors make a real difference. APS has refined the push-pin bolt system for enhanced reliability and power, pushing between 330 and 360 FPS using 0.2g BBs. That’s some solid energy for a shotgun that’s lobbing a dozen rounds in a single shot. The modified cradle and loading port are reinforced too, making it far more skirmish-friendly than the earlier MKI models.

The real star of the show? The CO2 Smart Shell system. Instead of housing the gas internally like a typical airsoft AEG or GBB shotgun, each shell is individually charged. This means you can carry and load them like real shotgun shells — and swapping them mid-game feels incredibly slick. Whether you’re using the standard Smart Shells or going for higher capacity with an 88g adapter setup, reloading is clean, fast, and doesn’t leave you stuck fumbling with mags or valves.

Other neat touches make this airsoft gun stand out even more. The fibre optic front sight offers fast target acquisition, even in lower light. There’s a built-in rail adapter on the barrel mount too, letting you bolt on a light or red dot without hassle. And for the realism nerds, the Salient Arms-licensed trademarks add that finishing touch — because who doesn’t appreciate a bit of detail when you’re shell-ejecting your way through a CQB maze?

In the hands, it balances well. At 2.7kg, it’s hefty enough to feel like a proper firearm, but not so heavy it becomes a chore. Length-wise, it’s around 1 metre, giving it that classic long-gun presence — perfect for players who like a bit of intimidation factor when breaching rooms or holding angles.

If you’re the type who plays with a bit of flair, who likes the drama of flying shells and thunderous pump-action reloads — this shotgun’s going to tick all your boxes. The APS CAM870 Marine is bold, brash, and built to dominate the CQB scene with pure mechanical satisfaction.
