Anyone who owns one, or is planning on buying one, MAKE SURE you tighten the top-most two screws on the back of the mag. They hold the feed lip assembly together and if they come loose, as they do during normal play, the feed lip will not hold properly. I tightened mine up as soon as I bought them and they feed PERFECTLY. The only way you lose a round out of these mags is if you load up, and don't fire all 29 rounds. Then, ONE will drop out of the feed nozzle area inside the gun. It is NOT a fault of the mag. All AEGs have this problem as far as I know. The feed lip is very stiff at first, but loosens up after a few loads/unloads and remains, to the best of my knowledge, working like a dream. Both a pro AND con is that the mag release causes them to drop from the gun. This is good because it facilitates fast reloads; bad because the mags have a very open design and will fill with dirt if you miss catching it. Overall 4.7/5. Will round up to 5.
Both of mine feed perfectly
Lock into the cm030 with a very crisp and sturdy sound
Adds nicely to the weight of the gun
The screws need to be tightened every once in a while during normal use
Tended to release all the bbs loaded while breaking in
Open design will fill easily with debris
