The APE AMBI  Series Lower receivers are built to run and function as flawlessly as one would expect a quality American made rifle component to function. They  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. The Lower receiver kit will ship with all proprietary ambidextrous controls installed and include our dimpled take down/pivot pins.

**Due to the design of the Ambi Bolt Catch/Release, the lower is NOT Compatible with certain triggers that utilize anti-rotation pins that use external screws or plates. We have developed a low head pin to be used with CMC Triggers. Standard GI type triggers, Drop in triggers that use standard pins, and Geissele triggers WILL work with with this lower.** Please note that ADM DUTY SERIES Lowers *may not* be returned for cosmetic issues, but are backed by our standard warranty guaranteeing 100% functionality and customer satisfaction. Weight: 11 oz

    Let’s be honest, it’s all about the look. You already know ADM makes a solid product. I have this paired with an ADM upper with a 14.5 Criterion barrel and Ripcord 13.75 LDR 1.5 rail. This is now my ‘GPR’ build with a TA02 on a Unity Cog mount. Only waiting for Acro P2s to come back in stock and that will be my offset/backup sight for this build.

    I’d been waiting for a while to grab an ADM4 lower; Ape doing a run definitely got me excited. What more can I really say? It’s one of the best ambi lowers available and the one I got is no exception. Mine’s already rattlecanned and installed on a build that had been waiting on an ADM lower for years (I’m a poor person). No regrets.

    Been rocking ADM lowers for about 6 years, in my opinion the best ambi lower on the market, grabbed one as soon as I saw Ape did this special run.
