Post front and four-position drum rear sights, with the "HK33" model and "IB" date markings on the left side of the magazine well, importer marks on the right, and the Fleming markings on the right rear under the trigger housing. The receiver is the "hinge pin" pattern with functional paddle combat magazine release, with a 1981 "IB"-dated bolt carrier welded up and reshaped to engage the auto sear, ambidextrous pin pattern trigger pack in safe/semi/3-round/full auto configuration, and a deluxe pictographic 4-position lower trigger group with red marking filler.
