Manufactured in limited quantity during a brief window in the 1980s, only about 200 of these commercial import L1A1 rifles made it into the United States. Manufactured by the Lithgow Small Arms Factory, these commercial L1A1s use receivers configured to prevent installation of an auto sear and were imported by Joe Poyer's Antique Arms of California. Post front and folding adjustable peep rear sights, with a long birdcage flash hider/knife bayonet lug, hand-adjustable gas system, 2-position selector switch and smooth "coachwood" furniture. The top cover doubles as the mounting point for a Trilux L2A2 infantry optical sight, and the right side of the upper receiver bears the Poyer import mark and inventory number "AUS 21". The trigger housing, bolt and bolt carrier bear the matching number "A43749". A canvas sling and an extra magazine are included.
