Picture of ADM4 MOD-1


The ADM4 MOD-1 is American Defense Manufacturing's base configuration rifle. Our patented, fully ambidextrous controls allow you to actuate the bolt catch and release lever along with magazine release from both sides of the rifle. Each function of our ambidextrous controls is accessible while maintaining constant contact with the rifle grip for maximum effectiveness during duty or recreational use. Our MOD-1 rifle line includes the ALG ACT trigger, MIL-SPEC 5.56mm barrel and A2 style flash hider. The ADM4 MOD-1 is built the to the same specifications as our standard UIC MOD-1, but features a slick sided magazine well for the more traditional AR15 look.

NOTE: ALL FIREARMS MAY HAVE up to a 6-8 WEEK LEAD TIME AFTER RECEIPT OF FFL. All firearms are Built 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.
