This video explores Heckler & Koch's lesser-known 5.56mm firearms, the HK33 and HK53. Introduced in 1968, the HK33 is H&K's adaptation of their roller-delay system to the 5.56mm cartridge, featuring a standard rifle, a shorter HK33K, and a compact HK53 "submachine gun" variant with an 8.3-inch barrel. While not adopted by major global militaries, these firearms found use with forces in Malaysia, Brazil, and Thailand. The description also includes links to the creator's Patreon, Floatplane, and merchandise store.
