American Defense ADM4 Features The American Defense ADM4 is built on a billet aluminum fully ambidextrous upper and lower receiver set machined to the same specifications as the company s standard UIC Mod 2 giving shooters proven receiver geometry in this configuration. The 14.5 barrel is pinned and welded with a muzzle device to reach a legal 16 overall length letting shooters run a shorter more maneuverable barrel profile without running afoul of NFA barrel length rules. This pinned and welded configuration is a popular solution for shooters who want the handling benefits of a short barrel in a rifle-length package. The slick sided magazine well distinguishes the ADM4 from other American Defense models while retaining the same rugged receiver construction. Finished in a durable matte black coating the ADM4 stands up to hard use in training or duty environments without showing wear prematurely. The rifle ships complete with a 30-round polymer magazine so shooters have everything needed to load and run the rifle immediately. Fully ambidextrous controls make the ADM4 comfortable to operate for both right and left-handed shooters a feature not found on many AR platforms in this price range. This rifle is available for sale at GrabAGun for shooters who want a billet-receiver AR built on proven American Defense engineering.
