Abstract: My invention, titled “The Brass Magnet”, is a device, which can be utilized by anyone participating in the use of firearms, whether, civilian, military, or law enforcement. The device will be used to collect the spent cartridge casings, after they have been extracted from a firearm. The device will be constructed of a handle which is attached to a cylindrical shaped drum. The drum is made up of spokes, which are spaced slightly smaller than the cartridge case. The device will be rolled over the area where the spent cartridge casings have fallen. The pressure or weight of the device will cause the casings to squeeze through the spokes, thus collecting the casings inside the drum, where they can be disposed of or collected.
