300 rds hi-cap metal magazine for M4 series - Black

High quality metal magazine from Delta Armory for M4, M16 etc guns.

The magazine is suitable for M4s from Delta Armory and Specna Arms and similar. It is made of high quality and durable polymer.

Holds 300 BBs, which are simply loaded through the upper closing hole in the magazine. Using a toothed wheel (which protrudes from the bottom of the magazine), an internal mechanism is extended to automatically feed the BBs into the gun. Thus, it is theoretically possible to fire the entire magazine in one full wind-up before firing.
