HK21 or Portuguese m/968: The H&K G3 Grows into a Light Machine Gun
This video delves into the Heckler & Koch HK21 light machine gun, also known as the Portuguese m/968. It explores its development as a companion to the iconic G3 rifle and its adoption by Portugal. The description highlights the HK21's mechanical similarities to the G3 but details its modifications for LMG use, including a reinforced receiver, heavier buffer, enhanced sights, and a quick-change barrel. The video notes the original HK21's dedicated belt-fed design and its competition in US LMG trials, where it lost to the FN Minimi. Special thanks are given to Bear Arms in Scottsdale, AZ for providing access to the rifle.
