Premium Licensed Construction and Finish

This shotgun carries the prestige of Salient Arms International licensing, showcased through authentic trademarks and the inclusion of high-performance aesthetic features. The core of the rifle features a robust Metal Body receiver, barrel, and magazine tube, giving the shotgun a realistic weight of approximately 2.7 kg. The high-quality Multicam finish on the receiver is visually stunning and ideal for operators running the popular camouflage pattern. Internally, the rifle boasts a Titanium Coated Push Pin MKIII Bolt and a Stainless Steel Carrier Plate, ensuring both premium looks and enhanced durability.

The CAM MKIII Shell Ejecting System

The CAM MKIII system represents the third generation of APS's groundbreaking shell ejection. Gas is now charged directly into the shells (compatible with MKI and Smart Shells), rather than the bolt, drastically improving power and consistency.Upon firing, the CO2 propels up to 12 BBs in a wide shower mode (320-360 FPS), making it a formidable CQB tool. The ultimate satisfaction comes from the functional pump-action cycle, which loads the next shell from the 7+1 round capacity tube and throws the spent shell clear—a feature that provides unmatched immersion for Milsim and training enthusiasts.

Tactical Ergonomics and Component Upgrades

Beyond the realism, the SAI package includes functional upgrades: a high-visibility Fiber Optic Front Sight for rapid target acquisition, and a Magpul-style forend and buttstock (often featuring stippling) for superior non-slip handling. The included Barrel Mount with Rail Adapter allows for immediate mounting of a tactical light or laser. The CAM MKIII-SAI-BKMC is the definitive choice for players seeking a unique, powerful, and iconic close-quarters weapon.

You shouldn’t have any doubt about Salient Arms Products. SAI has long been famous in making upgrade parts for real firearms. Nowadays, SAI is a trademark of high quality upgrade and innovation. In 2016, APS granted the license from EMG and SAI to make a superb 870 that is designed for the perfectionist. This shotgun featuring:

Most shell ejecting shotgun users will likely tell you that the fun of the immersive realism of the operation vastly outweighs any inconvenience caused by having to go collect the shells afterwards. However, whatever your stance, everyone must agree on the fact that this is probably one of the coolest airsoft innovations we’ve had in the last few years. This has been designed to almost entirely function like a real shotgun, even down to preparing your shell loads. APS listened to users of their previous Mark II design and made some big changes to improve it. The co2 charge is no longer done into the bolt carrier. The shells hold the co2 charge and as many BBs as you so feel works best for your style of play and how much of a spread you want, 12 is the maximum recommended.  You then insert a paper topper to prevent them from rolling out and load them into the magazine tube like you would a real one. There’s no need for inner barrels and hop-up chambers as all of the BBs are expended at once in one shot out of the 18mm diameter outer barrel. Rack the pump to eject the empty and load the next one. Charging the co2 directly into the shells means the shotgun is capable of delivering much more power than the previous version. This improves the system tenfold and makes it so much more practical. It’s a bit of a CQB beast and a must have for any collector or player who enjoys the realism. Metal parts include the internals, receiver, barrel, magazine tube, trigger guard, trigger, and action. Giving it a good heft and ruggedness, adding to the realism. The multicam finish is excelent and a really nice touch. Just be careful where you put it down as you might lose it.
