Nerf tactical rail to arduino mega

This is an adapter from a Nerf tactical rail to an Arduino Mega, as well as a camera from Waveshare.com, link

It does have holes in a relatively hard to access place, so make sure you can get them out, because otherwise you won't be able to put the camera in or get the wires through

Feel free to comment, I'd love to hear more about what I can fix.
