PTS® EPM1-S RX Enhanced Polymer Magazine

20-Round Look × 170-Round Capacity × Industry-Leading Feeding Performance

The EPM1-S RX is the refined version of the classic PTS EPM1-S. It retains the original 20-round short magazine profile and high 170-round capacity, while featuring re-engineered internal mold designs to further optimize dimensional accuracy and BB flow, thereby enhancing overall feeding performance.

The new EPM1-S RX features a gray internal shell marked with "EPM1-S RX" to differentiate it from the previous version.
