💡 Why I Designed This:
I created this because I was frustrated with slow, uncomfortable manual loading and having to carry bulky ammo containers. This design allows you to carry multiple compact magazines, each preloaded with 6 rounds, so you can reload quickly without slowing down. I also wanted a cleaner alternative to existing speed loaders that mount directly onto the marker, which can be bulky and affect the look and handling. This model has been tested and works well, but I’m open to feedback and future improvements from the community.
