Post front and 4-position drum rear sights, bird cage flash hider on the threaded muzzle, textured forearm with folding metal bipod, "S-F" marked trigger group and a polymer stock. The right side of the magazine well has the "HK Inc" import marks and the left has the model, serial number, caliber and "eagle/N, HK, antler" commercial proofmarks. With an extra forearm, two extra buttstocks (one fixed, one telescoping), frame-mount bipod, cleaning kit, manual, folding carry handle, elevation adjustable rear sight, spare gas tube plug, sling swivel, and seven extra magazines.

Excellent, with 95% of the original black finish, showing some light handling marks overall on the metal and stock. Some mild handling marks on the extra furniture. Mechanically excellent.
