Mid-cap magazines require special preparation before first use. Steps to be taken:

- When using for the first time, the magazine should not be fully loaded with BBs.

- Before first use, the magazine should be oiled with silicone oil for better function.

- On first use, the magazine should be loaded with a few BBs and then cored. After that, the magazine SHOULD be loaded with 10 BBs more than the first time and then cored. The activity should be repeated until the full magazine capacity is reached.

- Remember: When storing the magazine, it must be empty.

- Remember to oil the magazine regularly with silicone oil.
