Matrix Gen. II Steel 3000rd Electric Auto-Winding Drum Magazine for AK Series Airsoft AEG
by Daryl D. Date Added: May 30, 2012
Purchased 2 of these units for echo1 redstar ak47.

The problems:
1. Cheap junk electric motor.
2. Does not feed fast enough with the battery pack it comes with.
3. Will fall out of the gun. It did this on 4 different echo1 redstar ak's.

The good and fixes:
1. Easy to work on to upgrade. Although I do have a full machine shop, so that does help. Replaced junk electric motor with new 12V motor from jameco electronics. This new motor is 3 times faster on its' rpm's. This fixed problem #1.
2. Since it is steel I was able to mount a new battery pouch on the outside. Manufactured and wired up a 4 C123 battery pack. This is wired in series. With the new motor and battery pack, I do not have to stop firing until I run out of bb's. Also the battery pack has lasted 5 full game days without replacement. That is somewhere around 12000 to 15000 bb's. Problem #2 fixed.
3. The drum is steel not pot metal (aka zinc) construction. Welded a piece of metal and shaped it and fixed problem #3. Now it stays in the gun very securely.

So in a nutshell if you have a $1000 mill, $300 welder, skills to use them, can solder and have $50 for parts, you can make these magazines something to be reckonded with.
