The Marksman Magazine has a similar appearance to a traditional M-16 Metal Box Magazine.

This magazine can be used in both Geltactical Marksman M4 and Silverback M4 Gel Blaster Rifles.

Note: After use, make sure you shake out all remaining gels and leave the flap/cover open to allow the magazine to dry out properly so condensation does not occur and rust out the internal gearbox.
