ADM4 Competition Rifle

Built on a billet aluminum, fully ambidextrous upper and lower receiver set, the ADM4 Competition Rifle is the top of the line Competition Carbine for ADM. These Rifles are currently being built with standard UIC Upper Receivers with Forward Assist and Ejection Port Door Kit.

NOTE: ALL FIREARMS CURRENTLY HAVE A 6-8 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 FFL@ADMMFG.COM.

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.
