Arcturus M4/16 airsoft midcap 130/ 30 rounds EMM Variable-Capacity

Arcturus M4/16 airsoft midcap 130/ 30 rounds EMM Variable-Capacity

midcap polymer magazine with variable capacity. EMM or Enhanced Modular Magazine means that the design of the magazine allows you to easily change the capacity of the magazine from 130 rounds to a more realistic 30 rounds and to dismantle the magazine for maintenance.
The shell and the magazine foot are made of reinforced polymer. Particularly noteworthy is the fact of the extended feeder reducing the number of BBs left in the chamber after firing the magazine and the side inspection window making it easier to determine the number of BBs in the magazine.
