ARES SL-03 Universal BB Loader for M4/M16 Airsoft AEG and GBB Magazines w/ BB Bottle Adapter

"My first loader for Airsoft. Took a second to figure out but reliable.

"Great bb loader. For Aegs be sure to pull out little tab. I had 4 magazines filled in less 5 minutes. The EMG bio bb bottle fits the loader perfectly.

"Dose not work with matrix 50rd gbbr mags a better description of compatibility would be nice. I believe it's because of the feed lips. I don't think you can top load the matrix mags and BB can only go into the front of the feed lips

"Does not work with Double Eagle 35 Round MWS GBB magazines.
