Description

This semi-automatic rifle is built on a lightweight MAG Tactical Systems MG-G4 lower receiver and chambered in 5.56 NATO. The firearm features a two-tone aesthetic with a flat dark earth finished lower receiver and a black finished side-charging upper receiver, which features a charging handle marked BCA. The rifle is equipped with a 16 inch barrel tipped with a birdcage-style flash hider and a slim black M-LOK compatible handguard. Furniture consists of a Magpul MOE adjustable carbine stock and a Magpul MOE pistol grip, both in black. Sighting is provided by Magpul MBUS flip-up front and rear sights attached to the integrated Picatinny rail. The rifle includes one black 30-round polymer PMAG-style magazine and a quick-detach sling swivel on the forward left side of the handguard. Verbatim markings on the left side of the receiver include MAG Tactical Systems LLC Newburgh, IN MG – G4 CAL – MULTI S/N : MTS14420. The right side displays the MAG Tactical Systems logo with a crosshair. The barrel is marked 5.56 NATO. Note – All firearms require a federal 4473 background check.


Condition report:

The rifle is in good condition, exhibiting minor surface wear and handling marks consistent with moderate use. The finish on the receivers and handguard shows light scuffing and minor finish loss at the high points but remains largely intact. The bore is bright with well-defined rifling. The action appears to function correctly when cycled manually, though we have not function-tested this firearm. The Magpul furniture and magazine show standard handling wear but are free of cracks or structural defects.
