WE – M4 Co2 Magazine – Black

At the very top of the magazine is a button labelled “bolt release.” This button, when used, causes the bolt to lock back into place at the conclusion of the firing cycle, indicating that the magazine is empty. By adjusting the location of the switch, it is possible to turn off this feature.

This magazine is offering a more powerful recoil experience and consistent performance throughout the year thanks to Co2 gas.

Because doing so will extend the life of your magazine, we can’t stress enough how important it is that you use 28-30 bb’s when filling the magazine. When you initially buy the magazine, it will be difficult to put ammunition into it; but, as time passes, the spring will get less powerful, and the magazine will become simpler to use.
