Cybergun Licensed Metal Magazines for M4 / M16 Series Airsoft AEG Rifles (Model: Colt 300rd Hi-Cap)

"Perfect midcaps for G&G F2000. Mag locks into place and feeds well!

"Really nice sturdy metal mags. Not a single complaint.

Note: they are about a centimeter longer than the average m4 mag

"I bought the FN Herstal one for my G&G FN2000 and it fits and feeds perfectly, it also feels nice and hefty / stury (it is made of very nice quality stamped metal). I saw in another review that the COLT one in this same listing also fits (they are identical it looks like). So if you dont care about what "liscense" it is you can just get the colt one. These latch into the mag well snugly and satisfyingly but not too snug where inserting or removing a mag is difficult. I definitely recommend these for their feel and quality, and more universal fitment due to the shorter spring release part that sticks out.

These mags have the shorter spring release tab protrusion on top so they dont interfere with the screw on the AEG gearbox houseing in the G&G FN2000. Normally you can only really use Hi-Cap mags in the G&G F2k since all hicaps have that shorter spring release tab (to allow space for the fill hole opening) but to use midcaps you have to find the few midcap mags that also have the shorter protrusion. The F2000 also seems to feed better with metal stamped magazines than plastic mags.
