ADM4 Lower Receiver, Complete-SL Stock

ADM4 AR-15 Pattern Complete Lower Receiver featuring Fully ambidextrous controls featuring a right side bolt catch and release lever and left side magazine release. Functionally, this is the same lower as our standard UIC Lower Receiver, however it features a classic AR-15 slick sided magazine well that is great for retro builds, custom laser work or NFA engraving.

NOTE: ALL LOWERS CURRENTLY HAVE A 4-6 WEEK LEAD TIME AFTER RECEIPT OF FFL. CERAKOTE WILL ADD AN ADDITIONAL 3 WEEKS TO THIS LEAD TIME. 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.
