Description

For those of you looking for some spring loaded havoc in CQB, CYMA brings us the CM.351M M870, based on it's iconic real world counterpart, but with a stockless design keeping this shotty nimble and agile, while the full metal alloy construction giving it rough and ready capabilities in those intense CQB engagements.

Don't let it's compact size fool you, the M870 still has that OOMPH you'd expect from a shotgun and has a host of notable features ready to take control of any CBQ mission.

A big draw to this weapon is the realistic pump action loading, with the weighty cocking mechanism  and satisfying sound every time the rounds are loaded, ready to breach through a room to take down any insurgents. This sweet action is achieved by pulling the pump fully back, then fully forward to load each shot.

Another major feature of the M870 is the Tri-shot functionality, meaning every time the shotgun it cocked, 3 BB's are loaded to fire all at once. The shotgun also has a clever method of achieving this triple shot; Instead of firing a bunch of BB's 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, but more importantly, giving you the wider shot dispersal, causing some real havoc!

Found at both the front of the pump, as well as below the grip are the sling mounts, meaning you can attach a sling of your choice to allow for quick shoulder carrying, should you find yourself switching to an alternate weapon and need the shotgun secured when you're moving from objective to objective in a hurry.

The shotgun is constructed with a polymer grip, receiver, pump / lower, and with alloy barrels and trigger. 

Loaded from the bottom, just like the real thing, the M870 with a single shotgun shell styled magazine for that added realism, each shell holding approximately 30rnds for 10 triple shot spreads. Another nifty 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. 

This variant features a stockless design, to reduce weight when manoeuvring the gun, while also making the M870 more compact in those tight CQB environments; The added ease of movement might just be that little extra that keeps you fast and agile in those smaller encounters.

This is the perfect shotgun for those of you just getting into AIrsoft skirmishing and fancy a compact CQB rough and tumble type of shotty or for those more seasoned player looking for a more interesting secondary weapon, working great with a Shotgun Scabbard should your main weapon become inoperable. 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!
