USGI M4 / M16 / AR15 30-round EPM brown aluminum magazine 

The Enhanced Performance Magazine (EPM) from Center Industries.

 

Army engineers and scientists optimized the EPM to work with the M4/M4A1, M16 rifle, and standard military 5.56mm small arms round, the M855A1. The M855A1, known also as the Enhanced Performance Round (EPR), has been in use since 2010.

Following the EPR's release, engineering tests of M4/M16 rifles firing the M855A1 showed that the weapons were sensitive to the EPR's steel tip. A Picatinny Arsenal, N.J. engineering team subsequently made a design change to the magazine that corrected this issue.  The EPM eliminates weapon wear caused by the steel-tipped M855A1 at the upper receiver/barrel extension interface, a condition discovered during laboratory testing. 

The EPM is a brow to tan-color and has a blue-gray follower. The latter is the spring-loaded plastic component that positions each round up into the lower receiver of the weapon. Each magazine holds a maximum of 30 rounds.

Important:  The EPM magazine has a more snug fit than other magazines.  It is designed for use in military grade lower receivers. If you are using a commercial receiver, the fit might be too snug to drop release.  We do not guarantee fit with non-military grade forged receivers.  This is not a defect, it is a design, and we will not accept returns of these mags.

 

Magazines considered high capacity are controlled by the ATF and/or local jurisdictions and are not available for purchase/shipment in all areas.
