Kel-Tec Model SU-16, 5.56mm cal. auto folding survival rifle. Serial# NDW38. Excellent like new condition. Perhaps test fired. A great Bug-Out or survival rifle that folds in half for easy storage or carry. 16” barrel with an excellent bore. Fixed sights. Dark Earth polymer stock and frame have 99% finish. Matte black barrel is 99%. Quick pull tack down pin. Handguards fold down to be used as a bi-pod. Two 10-rd. magazines - these stow in the stock. Also accepts Ar-15 mags. Picatinny rail on the top of the receiver. A very well thought out and designed little carbine. I personally have one in my own Bug-Out kit. Includes the manual.
