The EPM (Enhanced Polymer Magwell) is a lightweight, low-profile flared magwell designed to improve reload consistency without compromising the handling or footprint of the rifle. Made in the USA with American made materials. Lifetime Warranty. Hardware and Allen Key Included.  Compatible with all major magazines including Magpul D-60 Drum magazines.

The geometry of the EPM significantly expands the usable magwell opening to aid magazine insertion under stress, adverse conditions, and reduced visibility such as under night vision, while avoiding unnecessary width or bulk at the lower receiver. The design improves reload forgiveness without creating snag points or interfering with existing controls.

Constructed from an engineering-grade, glass-filled nylon polymer, the EPM uses the same class of material found in high-impact duty applications such as cordless power tool housings and military laser enclosures, including the PEQ-15. This material offers excellent strength, stiffness, and impact resistance while remaining exceptionally lightweight. It is highly resistant to weather, moisture, and extreme temperatures, allowing the EPM to perform reliably across a wide range of environmental conditions. At just 26 grams installed, it adds almost no mass to the rifle while delivering a meaningful functional advantage.

The EPM installs easily with no permanent modification to the rifle and introduces virtually no drawbacks while providing a clear performance benefit through improved reload efficiency in demanding conditions.

This version is made for fitment on standard milspec lowers and has been successfully tested on the following: Aero Precision, Colt, FN, and Geissele but should fit on any standard, non-proprietary forged lower receivers.

Please note that unusual or non standard trigger guards could cause fitment issues, however it has been successfully tested with a standard milspec guard, magpul, BCM, and should work with most models out there.
