Description
Tokyo Marui M870 Breacher Gas Tank
This is a spare gas tank for the Tokyo Marui M870 Breacher gas shotgun. Tokyo Marui is the Japanese manufacturer behind some of the most consistent and reliable airsoft replicas available, and its M870 series is one of the best-loved pump-action shotguns in the game. The Breacher is the short, pistol-grip version, designed for close-quarter and indoor play.
The M870 gas shotguns are powered by a separate gas tank fitted inside the gun, rather than by gas in the shells. A spare tank lets you carry a ready-filled replacement, so you can keep playing rather than stopping to refill. One retailer quotes around 50 shots per fill.
Using a spare tank
For skirmish days, having two or more tanks means you can swap a full tank in when the first runs low, rather than refilling in the middle of a game. Fill the tank from your gas can as you would the original, keep it upright while filling, and do not overfill.
Fitting
Remove the empty tank from your shotgun and fit the spare in exactly the same way as the original. Always check the shotgun is unloaded and pointed in a safe direction when changing tanks.

Care and maintenance
