Compact Power and Full Metal Construction:
The Tokyo Marui M870 Breacher is the ultimate shotgun for playing in tight spaces and needing maximum agility. To power this compact monster without the bulk of a fixed stock, Marui designed this specific Removable Gas Tank. Made from a heavy and resistant metal block, it fits directly into the pistol grip of the gun. High-precision valves deliver a constant pressure to the firing system, ensuring that your 3- or 6-shot grouping is always lethal and uniform.
The Advantage of Rapid Breach:
Running out of gas during "slicing the pie" (opening corners in a room) is fatal. This tank is completely removable: you can carry two or three full loads in your gear. When you feel your Breacher's power dropping, simply detach the empty tank from the grip and insert a new, full one in just a few seconds. A tactical system that makes gas bottles on the field a distant memory!
THE BREACH EXPULSION TRICK (Pro-Tip Breacher): Here's a secret from true CQB professionals. Pressing the release lever under the grip of your Breacher when there's still some gas left in the tank, the pressure will act as a spring, "spitting" the metal block into your hand! We recommend never waiting for the last shot at empty: change the tank just before it's completely drained to take advantage of this burst and reload at lightning speed.
IT'S NOT A BB MAGAZINE! We repeat this because the mistake is classic: this heavy metal block contains ONLY the Green Gas. To shoot, you'll still need to purchase and insert the appropriate cartridges/bullets (caliber 12) into the magazine under the barrel.
Saving O-Rings (Gas Maintenance): The brass valves are equipped with delicate rubber O-rings. If you store the empty tank after a game, the rubber will dry out irreparably and start leaking. Always leave a light spray of Green Gas inside: the internal pressure and lubricating gas will keep the O-rings perfect for years.
