Our take: Spare 20-rd magazine for the Wellfire M16A1, M16A2, M4 RIS, M4A1, and TacSpec M4 RIS spring airsoft rifles. This magazine has a large 450-rd storage compartment for additional airsoft BB's. This compartment feeds directly into the spring loaded BB chamber, which gives you easy access to additional ammo without wasting time fully reloading the magazine. To quickly reload the magazine, simply lock the feeding spring to the bottom of the mag and shake the magazine while it is facing upside down. This spare magazine is a great addition for longer games with less time to reload.
