The Echo1 P90 boxmag is designed to increase the firepower of your airsoft P90 AEG. The E90 box mag setup is designed to be used with an M4 style hicap, and carries over 1500 rounds.

With an M16 hicap installed, the Echo1 P90 box magazine holds over 1500 BBs. The top reservoir on the P90 is filled with ammo, which pours down into the M4 hicap. The M4 hicap is wound to feed the BBs into the P90. This setup has one major advantage over traditional P90 hicap magazines. When a normal P90 high capacity mag is inserted, the mag cannot be wound. By using the E90 boxmag, the mag can be would at any time, making it easier to keep your E90 loaded.

Echo1 E90 Boxmag Features:

-Large Internal Reservoir
-Requires M4 Hicap Mag
-Easily Load and Use your P90 or E90 AEG 

The P90 box mag will not work with M4 Midcap magazines without modification.
