The Cyma Tri-Shot Sawed Off Shotgun (CM351)

The Cyma CM351 Sawed Off Short Barrel Tri-Shotgun provides unparalleled effectiveness and realism in the ultra-compact class. This shotgun is specifically engineered for the aggressive player who demands maximum maneuverability and devastating firepower in tight, close-quarters environments.

The robust design and reliable spring action solidify the Cyma Tri-Shot Sawed Off Shotgun as the mandatory choice for budget-conscious breachers.

Extreme Compactness for Breaching

The most distinctive feature of the CM351 is its Sawed Off, stockless design which reduces the weight and size when maneuvering the gun, while also making the M870 more compact in those tight CQB environments.. This configuration results in an extremely short overall length, making the shotgun exceptionally quick to wield and transition.

This compactness is crucial in CQB, preventing snagging on door frames and cover, and allows the shotgun to be easily maneuvered or holstered as a highly effective secondary weapon.

The minimalist profile sacrifices nothing in functionality, focusing entirely on speed and utility.

Innovative Triple-Barrel Tri-Shot Mechanism

A major functional feature of the M870 is the Tri-shot functionality, meaning every time the shotgun is cocked, 3 BBs are loaded to fire all at once. The shotgun has a clever method of achieving this triple shot: instead of firing a bunch of BBs at once through a single barrel, the gun has three barrels allowing it to shoot up to 3 BBs at once to create a spread pattern for more realism.

More importantly, this gives you the wider shot dispersal you need, causing some real havoc! The fixed hop system is optimized for consistent performance within the intended close-range engagement envelope.

Spring Action Reliability and Simplicity

The CM351 operates via a highly reliable Spring-Powered Pump Action. This system guarantees mechanical simplicity, low maintenance, and 100% operational consistency regardless of external factors like temperature or gas pressure—unlike GBB or HPA shotguns.

While requiring manual pumping for each shot, this action ensures the shooter always knows the status of their weapon. This robust, reliable mechanism provides decades of dependable use.

Metal/Polymer Build for Durability

The shotgun is constructed with a polymer grip, receiver, pump / lower, and with alloy barrels and trigger. This combination provides durability where needed (the firing components) while maintaining an overall lightweight platform- 1.5kg. The chrome mock bolt and spring-loaded magazine door add to the visual fidelity. The robust nature of the design makes it perfect for those seeking a compact CQB rough and tumble type of shotty.

The reliable feed system uses standard, widely available Airsoft Shotgun Shells (30 BBs per shell), which are stored in a small internal reservoir.

Shell Loading Realism and High Value

The shell-fed system adds an essential layer of operational realism often sought after by Milsim players. Despite its high performance and robust build, the CM351 maintains an accessible price point.

The low cost, coupled with its unparalleled agility and dependable action, ensures the Cyma Tri-Shot Sawed Off Shotgun is the definitive, high-value entry point for anyone needing a devastating, reliable, and unique close-quarters primary or secondary weapon.

Operational Realism and Built-In Shell Storage

A big draw to this weapon is the realistic pump action loading. The weighty cocking mechanism and satisfying sound every time the rounds are loaded, ready to breach through a room, are achieved by pulling the pump fully back, then fully forward to load each shot. Loaded from the bottom, just like the real thing, the M870 feeds with a single shotgun shell styled magazine for that added realism, each shell holding approximately 30 rounds for 10 triple shot spreads.

Another feature is that the front of the loading tube can be unscrewed to find enough storage for up to 3 shell type shotgun magazines. While not exactly quick access, it is however very convenient if you are not using a rig or are yet to get shell pouches, saving you from switching to an alternate weapon prematurely

Important Note

Special Instructions: Once a shell has been loaded into the shotgun it is very important to make sure the shell door is closed properly. If the weapon is racked with the door open it can cause it to snap off, leading to possibly losing shells during skirmish. Easy to use, and quick to load, the M870 is a budget friendly weapon that will clear rooms with no trouble; the trouble is saved for the enemy team!
