The magazine uses a 12g CO2 bulb which goes in the bottom of the magazine and is covered by a large flat bladed alloy release cap / cover. The magazine is also very easy to strip and maintain with only 2 screws holding the main components together. Once the magazine is empty your GBB weapon will also lock back until you change magazine. This bolt stop function can be disabled with the press of a button located on the top of the magazine.

Special Instructions:

We highly recommend that the magazine is filled using 28-30 BBs instead of the maximum capacity of 32, this is to increase the longevity of your magazine. When first purchased the magazine will be hard to fill, however, over time the spring will become weaker and the magazine easier to reload.
