HK43: The 5.56mm "Paramilitary" Rifle
The HK43 is a rare, early semi-automatic variant of the HK33, produced by Heckler & Koch in the early 1970s as a civilian export model. It shares the roller-delayed blowback action and 5.56mm caliber with its military counterpart but features a push-button magazine release and a permanently attached flash hider to meet US import laws. Extremely limited production, likely under 500 units, makes it a highly collectible firearm.
