These high capacity magazines from G&G hold 450 rounds and fit most M4 or M16 Airsoft AEGs. The G&G magazine is longer than a typical airsoft M4 magazine, but holds more rounds than a normal hicap magazine.
If you're looking for a magazine that lets you reload a little less often, or if you want to replicate the 40rd AR15 magazine, the G&G 450 round hicap is an excellent replacement magazine.
G&G M4 Gray Hicap Magazine Features:
-Full Metal Construction
-Expanded 450 Round Capacity
-Fits all M4 AEGs
