Enhanced ^ 2

The 'Umbrella' Enhanced PTS EPM 150rnd Magazine has a change specifically to increase feeding reliability with heavier weight BBs. A modifications automatically included in every EPM magazine sold as of January 2023. We install a spacer inside each magazine to ensure feeding with the heaviest of rounds in even the fastest AEGs.

We noticed that PTS changed their EPM design a couple times since inception. Including using a different follower, different spring guide rod, and even the main spring. However with these revisions we've noticed severe stuttering with weights such as 0.28, and higher.
