The MZ FDE variant pairs a black receiver set with FDE furniture and handguard for a clean two-tone look. The magwell carries the DB shield logo, and the ejection-port cover is marked "5.56 NATO." The rifle uses direct-impingement operation with a 2-position safety.
The 16-inch barrel is threaded and capped with an A2 birdcage flash hider. A free-float FDE M-LOK aluminum handguard with a short forward Picatinny segment provides mounting space while keeping weight forward balanced.
A flat-top A3 upper includes a T-marked 1913 Picatinny rail (T2–T12 visible), plus a forward assist and shell deflector. No iron sights are included, allowing the user to configure the top rail as desired.
The carbine-length collapsible stock rides on a carbine receiver extension, and the A2-style FDE pistol grip provides a familiar control layout. Capacity is 30+1 with 5.56mm NATO, and the rifle is manufactured in the USA in Cocoa, Florida.
Additional functional touches include the black receiver finish, FDE polymer stock and grip, and a listed length of pull of 11.0 inches in its current configuration.
