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

midcap metal 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 BBs to a more realistic 30 BBs and disassemble the magazine for maintenance.
The shell of the magazine is made of blackened steel. Particularly noteworthy is the fact of the extended feeder that reduces the number of BBs left in the chamber after the magazine is fired.
