Used HK 93 12(5) Prohibited Rifle 223-556 Semi-Auto Overview
Used HK 93 12(5) Prohibited Rifle 223-556 Semi-Auto;
In the mid to late 1960s, Heckler & Koch developed the HK33,
which was a scaled-down version of the Heckler & Koch G3,
but chambered for 5.56×45mm NATO. The HK33 entered production in 1968.
In 1974, a semi-automatic version of the HK33 was introduced by H&K and also was designated the HK43.
According to H&K’s numbering nomenclature, the “4” indicates that the weapon is a paramilitary rifle,
and also the “3” indicates that the calibre is 5.56 mm.
Like the Heckler & Koch HK41, the HK43 had a NATO black finish,
which differed from the black phosphate or blue-grey finish of the later HK91/93 series,
and came with a short slim forearm grip.
Moreover, there were no proof marks on the receiver.
