Avengers 1200 Round Electric Drum Magazine for Airsoft AEG Rifles
(Model: M4 - Tan / Sound)

"I CAN CONFIRM that this fits King Arms PDW. The only problem is the bottom stuck out mag release but you can simply resolve this by pushing the bottom mag release pin out on the lower receiver and push the mag release into the receiver or remove it. But this does fit KING ARMS PDW MP5 MAG MODEL

"So bought this about 3 weeks ago, played my first game with it this last saturday,

This thing, atleast for the MP5 adapter is flawless.

I own an MP5K CM041L that i got from Taiwangun and right out of the box it comes with an extreme ROF. THis thing was able to keep feeding it flawlessly. I held down the trigger and kept the button pressed and i was able to just lay down constant fire.

This is a 5/5 Product to me. If you wanna rock a drum with an auto winder. This is for you.

"The mag fits my CM.011 g36c perfectly. It works flawlessly in semi but in full auto it only feeds 1-2 bbs per trigger pull. Mine does have 13:1 gears and running a 11.1 lipo. Field I play at only does semi so good for what I use it for.
