HK21 or Portuguese m/968: The H&K G3 Grows into a Light Machine Gun
This video delves into the Heckler & Koch HK21, a light machine gun variant of the iconic G3 rifle, and its Portuguese designation as the m/968. It highlights the HK21's development as part of a complete small arms package and its initial lack of adoption by the West German Bundeswehr, instead finding a significant early market in Portugal, who also licensed its production. The description details the mechanical modifications that differentiate the HK21 from the G3, such as a reinforced receiver, heavier recoil buffer, enhanced sights, quick-change barrel, and belt-feed action. It also mentions the HK21's competition in US LMG trials where it was ultimately outperformed by the FN Minimi, and notes its challenging recoil characteristics.
