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.
