The magazine for the Umarex CP99/Nighthawk 4.5mm is an original replacement for the magazine included with the air rifle.
The magazine, with a capacity of 20 BB' shotgun shells, has a solid metal body and a polymer foot for easy ejection from the pistol grip. After placing the capsule, tighten it with the lower knob, which will unseal it and release the gas.
Note that once the capsule is installed in the magazine, it should not be kept in the magazine for more than 48 hours, as the gas pressure can permanently damage the valve seals.
The magazine donner can be locked in the lower position, this allows convenient loading of BB'S balls by gravity directly from the pack.
