Fully 3d printed gun with functioning mag (DOES NOT SHOOT)

i made this to see if i can make a fully 3d printed gun, this is a small part of it and more of this will be coming soon, from what ive tested so far it can hold 3 bullets but im gonna continue working on this for later, you should weld the bottom part to the magazine using the 3d printer hotend.

Have to add this to not get taken down:
this is not a real gun, it does not shoot.
