Battle Arms Development Xiphos Complete Lower Features The Battle Arms Development Xiphos lower receiver is machined from aluminum rather than molded polymer giving builders a more rigid durable foundation for a 9mm pistol caliber build that accepts Glock pattern magazines. Chambering it in 9mm Luger makes it a natural fit for shooters who already run Glock magazines and want to carry that same magazine compatibility into a different platform. The receiver includes a manual safety adding a familiar rifle style control to a pistol caliber build for shooters coming from a traditional AR background. At just 14.2 ounces the aluminum lower keeps the completed build from becoming front or rear heavy once paired with an upper. Finished in a black anodized coating the Xiphos is built to resist wear and corrosion through repeated range use and field carry. Choosing an aluminum lower over a polymer frame can offer a different feel and durability profile for shooters who prefer a more rigid receiver under recoil. Because it is built specifically around the Glock magazine pattern it allows builders to standardize on widely available inexpensive magazines rather than a proprietary design. Shooters building a dedicated 9mm pistol caliber platform will find the Xiphos a well made precision machined option for the lower receiver.
