The PTS EPM E9 Magazine is a 110-round spring loaded magazine that features a constant-curve internal geometry for reliable feeding and a tough Dupont Zytel polymer outer body that will withstand the toughest field use conditions. PTS Syndicate's signature EP pattern has been implemented onto the shell to give the magazine a positive texture for better grip and tactile feel. The marking matrix is incorporated onto left and right hand side of the shell for personalized magazine identification use.
 
Like the rest of the EPM family of M4 magazines and the AR9 magazine, the EPM E9 magazine incorporates full load indicator to prevent overloading.   When the orange follower appears in the small see-through window which is located at both side of the shell, the magazine is fully loaded.
