American defense mfg adm4 duty series lower receiver ar15 ambi mag release lower 1

America Defense MFG has announced the roll out of their ADM4 Duty series Ar-15 pattern lower receivers.

America Defense MFG states “ADM4 DUTY Series Lower receivers are built to run and function as flawlessly as one would expect a quality American made rifle component to function.

ADM DUTY lowers are priced under our standard production lowers and are practically begging to be completed into a hard use rifle ready for all the rigorous treatment that a duty rifle can expect.

These lowers have minor cosmetic blemishes, but are 100% functional.

The ADM4 UIC DUTY SERIES billet 7075-T6 lower receiver features a Type III Teflon impregnated hardcoat anodized finish, is outfitted with our proprietary Ambidextrous magazine release, Ambidextrous bolt catch and release, and our dimpled Take down and Pivot pins.

The magazine well features reinforcing ribs that make the magazine well 40% stronger than mil-spec forged at only half ounce of weight change.

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.”
