We have learned about the release of the magazine previously but we were not allowed to post it until today... "The EMAG (Export MAGazine) is a lightweight magazine which features a number of aesthetic and functional changes from the original PMAG®. The PTS PMAG™ for SYSTEMA PTW is a 120 round compatible magazine which shows an advanced impact on resistant polymer construction.  While EMAG remains 100% compatible with the SYSTEMA AR15/M16 platform, its unique geometry is optimized for aftermarket SYSTEMA PTW HK 416 receiver. 

With excellent quality and special design, one of the obvious features of PTS EMAG SYSTEMA PTW is the transparent window showing dummy shells on the smooth surface and includes pop-off Impact/Dust Cover same as the PMAG GEN M2. We are excited to announce that PTS EMAG SYSTEMA PTW is now available. "
