WE Europe - Toucan Big Bird 25rd Co2 Magazine Kit - Black is a replacement magazine for WE Toucan Series magazines with a twist, these magazines accept Co2 Bulbs instead of Green Gas. The magazine is constructed from Alloy, and features a Double Stack Magazine Design, allowing it to hold up to 25 BBs at a time. Instead of the magazine being filled with Green Gas the base plate is removed and a Co2 Bulb is placed inside, this gives the magazine a more powerful kick, higher FPS and more reliability in cold weather. The magazine uses standard 12g Co2 Bulbs, and comes with a Co2 Valve Tool, Two Grip Extensions and an extra Back Strap Plug. This magazine will work on both the Big Bird Version, as well as the Little Bird Version, by simply attaching the magazine grip extensions on the magazine. This magazine is perfect for those Airsoft Skirmisher who want to make the jump to Co2, or for those who want that extra little bit of power and reliability during cold weather conditions.
