From PTS Syndicate we have the Enhanced Polymer Magazine for Sytema PTW M4/M16 AEG's in Black.
The PTS Enhanced Polymer Magazine (Systema PTW), or EPM for short, is a new type of Polymer Magazine for airsoft rifles. Built specifically for the Systema M4 PTW series AEG, the EPM is a truly unique magazine, inside and out. Externally, it features a rugged Dupont Zytel polymer shell. The magazine is designed with recessed panels for better grip, and unique magazine well guides that reduce snagging when the magazine is drawn from and reinserted into pouches. The front of the baseplate features a dot matrix which allows the user to mark the magazine with alphanumeric characters or pictograms for identification.
