American Defense MFG Introduces ADM4

12DEC2017 – NEW BERLIN, WI – American Defense MFG® (ADM) is proud to release our “ADM4” receivers and complete rifles. This design variant is purely aesthetic in nature. These lower receivers will retain our patented, fully ambidextrous controls that are intuitive in design and function. Perfect for retro builds (with modern features), NFA Engravings, and is also available to other manufactures wanting ambidextrous controls for their brand. Available now via our dealer network and direct from American Defense Mfg®.


ADM4 billet 7075-T6 lower receiver features a Type III Teflon impregnated hard-coat anodized finish, outfitted with our patented ambidextrous magazine release, ambidextrous bolt catch and release, and our dimpled take down and pivot pins. The trigger guard is ready for winter gloves without manipulation. Radii and chamfers throughout make this billet lower a marvel that stretches the capabilities of modern production CNC manufacturing. A 20-degree competition style mag well is concealed in the design, allowing lightning fast magazine changes. An integral upper/lower tension adjustment screw allows the end user to compensate for tolerance between your upper receivers and your favorite lower.

    Ambi catch and release is a very nice feature, along with the integrated flared magwell.
