Introduced in 1991. "HBAR" marked heavy crowned barrel with a long round ribbed forearm and adjustable pin front sight, A2 upper receiver with deflector, assist, and adjustable two leaf aperture sight, lower receiver with standard markings and a checkered pistol grip, and a smooth buttstock with a black nylon sling and a checkered trapdoor buttplate. Two lines of white paint have been added to the rear sight across the dials

Excellent, with 98% of the original blue finish. Some light handling marks are visible overall, along with some lighter spots on the buttstock. Mechanically excellent.
