These drones are for the sole purpose of making sure your weapon with an optic will fit the holster you have designed and built. Whether its for the width to see if the holster will interfere with the sides of the optic or if the hood is placed too far down. you can stick it to your folding drone when doing test fits. A cheaper alternative to purchasing all optics out there.
i will be adding more options as i scan or get ahold of files
