ONE MAGAZINE TO FEED THEM ALL

This mag stands on top of all the magazines we have ever used and it will probably end up being the same for you. Its 225 BBs capacity and reliant feeding, makes it the ideal magazine for sustained fights.

Time to reload?

Even with your mag inserted you can take a look at it and see if you have ammo left. Once you don’t see any BBs on the side windows, you have around 15 rounds left, before it’s time to reload.

To ensure durability, we used transparent polycarbonate inserts for the windows instead of a full transparent core, and implemented reinforced polymer for the core itself.

This way, you won’t have to worry about dropping your magazine or mag-flipping it into the closest wall (or teammate).

Just look down

It’s now as easy as looking down at your plate carrier or belt to know which magazine still has BBs and which one has already been used, in case you’re like us and always forget which mag you swapped in the mid of the action.

This bottom window tells you at least around 100BBs are left inside the magazine.
