gun design 1V2

This is a sci fi looking little gun i made in the garage, i made it for the sake of the looks, as i like to experiment with design and such. so it isnt very powerfull, it has a range of about 20 - 30 meters and can pierce cardboard.
The materials is collected at my school and components like the rail and magnet is bought. caliber is 10mm x 20mm.

i havent come up with a name or a backstory for it other than that EKSTRØM Defence made it sometime in the future.

I'd gladly accept opinions and critique on it, so i can evolve it and make it even better
Hope you enjoyed my creation.
