ADM4 Lower Receiver-Duty Series (BLEM)

ADM4 DUTY Series AR-15 Pattern 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 are the same as our tried and true UIC Lower, however they do exhibit cosmetic blemishes that will not affect function.

NOTE: ALL LOWERS CURRENTLY HAVE A 1-2 WEEK LEAD TIME AFTER RECEIPT OF FFL.

All firearms are Build To Order. The build process will begin when ADM has the order and a copy of the customer's FFL where the firearm will ship to. Orders will sit pending until the FFL is received. Please have your dealer email a copy of their FFL with the Customers Name and Order Number in the subject line to [email protected].

While American Defense MFG tries to stay current on all state laws, it is the responsibility of the customer to ensure that the firearm they are purchasing is legal to ship, as presented on our website, to their dealer of choice, and that the dealer is willing to accept the transfer.

All DUTY GRADE and BLEMISHED items are sold AS IS with NO RETURNS or REFUNDS. ALL SALES ARE FINAL.

ADM 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 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. The ADM4 DUTY SERIES 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 **SEE PRODUCT INFORMATION FOR ADDITIONAL PHOTOS**

Excellent Lower

As far as Ambi AR lowers go, this thing is excellent. I currently only have my MARS L from LMT to compare this to, and I think ADM compares favorably. Pros: Well built, exceptional fit & finish The offhand bolt catch/release can be *easily* manipulated with the trigger finger without compromising your position on the rifle - It's truly an excellent design, without a doubt the best I've used on an AR-15 The traditional bolt catch "paddle" is oversized and durable. It's easy to manipulate with and without gloves, no complaints here The tension screw eliminates upper/lower slop - excellent feature CONS: Really none inherent to the design. I'd prefer a forging over billet as its lighter and very strong, but I knew it wasn't forged going into buying it. This really is an excellent lower and I would pick it over a lot of the other competitors if you want a truly ambidextrous and no-gimmick lower.
