MILITIAMEN 5.56 / AR15 LOW-SHELF STRIPPED LOWER RECEIVER

There is a reason the Matrix Arms family of AR-15 lower receivers has been our #1 SELLER BY VOLUME.

With more than 1 million AR receivers manufactured to date and serialized OEM lower receivers produced for over 100 different firearm companies under their name logo and address, we have spent years manufacturing receivers trusted by customers throughout the industry. That same proven receiver is now available under our sister brand, Militiamen, at an even more aggressive price.

Militiamen with product line officially launched in 2026 is owned and operated by the same ownership behind Matrix Arms. As a Christian-based, family brand, our goal is straightforward: offer reliable American-made firearms at prices that make them accessible to more Americans to help defend against our rights being constantly infringed.

PROVEN LOW-SHELF DESIGN

One of the defining features of this receiver is its low-shelf fire-control pocket. Similar to that of an M16 pocket we incorporate even more removed material for ease of use with compatible parts and triggers.

Matrix Arms low-shelf receivers have developed a strong following among customers building a wide variety of AR-platform configurations, including builds utilizing compatible aftermarket trigger systems such as FRTs, Super Safeties/Super Selectors, and similar systems where lawful.

The AR-15 platform is built around modularity. Complete assemblies can be changed to accommodate different configurations and calibers while retaining the same lower receiver. Starting with a quality lower provides the foundation for virtually any AR build.

AMERICAN-MADE 7075-T6 FORGED CONSTRUCTION

Militiamen stripped lowers are CNC machined entirely at our facility in ‘Live Free or Die” New Hampshire, USA from American-made, mil-spec 7075-T6 aluminum forgings sourced from major U.S. forging companies such as Cerro, Brass Aluminum Forging, Mueller, and Cardinal.

7075-T6 provides an outstanding combination of strength, durability, and low weight. Each receiver is finished with a Type III Class II hardcoat anodized matte-black finish for excellent wear and corrosion resistance.

These aren’t an untested new receiver being introduced under a new name. They are built from the same manufacturing experience and proven receiver platform behind years of Matrix Arms production on the same machine cells that have contributed to making over a million receivers.
