This metal M4 hicap magazine from Classic Army beats every other brand of standard M4 hicap for capacity; coming in at a grand total of 460 rounds. Comparable magazines can cost between $30 and $40 and they'll still come up short in capacity. As with most hicaps, this magazine is loaded from the door at the top and wound using the toothed wheel at the bottom. 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 Classic Army 460 round hicap is an excellent replacement magazine.
Classic Army M4 Hicap Magazine Features:
-Full Metal Construction
-Expanded 460 Round Capacity
-Fits all M4 AEGs
