300-Round M4/M16 high capacity magazine - metallic shell. Compatible with AGM M4 and M16 airsoft guns.
AGM manufactured M4s always seem to have a bit of a tighter fit in terms of magazines, so Airsoft Megastore has decided to carry the 300rd M4/M16 mag OEM manufactured by AGM to guarantee fitment in AGM M4/M16 AEGs without wobble. Good quality and finish.
